6 Detailed Description

6.1 CPU

This fixed-point digital signal processor (DSP) is based on the C55x CPU 3.3 generation processor core. The C55x DSP architecture achieves high performance and low power through increased parallelism and total focus on power savings. The CPU supports an internal bus structure that is composed of one program bus, three data read buses (one 32-bit data read bus and two 16-bit data read buses), two 16-bit data write buses, and additional buses dedicated to peripheral and DMA activity. These buses provide the ability to perform up to four data reads and two data writes in a single cycle. Each DMA controller can perform one 32-bit data transfer per cycle, in parallel and independent of the CPU activity.

The C55x CPU provides two multiply-accumulate (MAC) units, each capable of 17-bit x 17-bit multiplication in a single cycle. A central 40-bit arithmetic and logic unit (ALU) is supported by an additional 16-bit ALU. Use of the ALUs is under instruction set control, providing the ability to optimize parallel activity and power consumption. These resources are managed in the Address Unit (AU) and Data Unit (DU) of the C55x CPU.

The C55x DSP generation supports a variable byte width instruction set for improved code density. The Instruction Unit (IU) performs 32-bit program fetches from internal or external memory, stores them in a 128-byte Instruction Buffer Queue, and queues instructions for the Program Unit (PU). The Program Unit decodes the instructions, directs tasks to AU and DU resources, and manages the fully protected pipeline. Predictive branching capability avoids pipeline flushes on execution of conditional instruction calls.

For more detailed information on the CPU, see the C55x CPU 3.0 CPU Reference Guide [literature number SWPU073].

The C55x core of the device can address 16M bytes of unified data and program space. The core also addresses 64K words of I/O space and includes three types of on-chip memory: 128 KB read-only memory (ROM), 256 KB single-access random access memory (SARAM), 64 KB dual-access random access memory (DARAM). The memory map is shown in Figure 6-1.

6.2 Memory

6.2.1 Internal Memory

6.2.1.1 On-Chip Dual-Access RAM (DARAM)

The DARAM is located in the byte address range 000000h - 00FFFFh and is composed of eight blocks of 4K words each (see Table 6-1). Each DARAM block can support two accesses per cycle (two reads, two writes, or a read and a write). The DARAM can be accessed by the internal program, data, or DMA buses.

(1) The first 192 bytes are reserved for memory-mapped registers (MMRs). See Figure 6-1, Memory Map Summary.

6.2.1.2 On-Chip Single-Access RAM (SARAM)

The SARAM is located at the byte address range 010000h – 04FFFFh and is composed of 32 blocks of 4K words each (see Table 6-2). Each SARAM block can support one access per cycle (one read or one write). SARAM can be accessed by the internal program, data, or DMA buses. SARAM is also accessed by the USB DMA buses.

04E000h – 04FFFFh 000C E000h – 000C FFFFh SARAM 31(1)
(1) SARAM31 (byte address range: 0x4E000 – 0x4EFFF) is reserved for the bootloader. After the boot process is complete, this memory space can be used.

6.2.1.3 On-Chip Read-Only Memory (ROM)

The zero-wait-state ROM is located at the byte address range FE0000h – FFFFFFh. The ROM is composed of four 16K-word blocks, for a total of 128K bytes of ROM. Each on-chip ROM block can support one read per cycle. The ROM address space can be mapped by software to the EMIF external memory or to the internal ROM.

The standard device includes a Bootloader program resident in the ROM.

When the MPNMC bit field of the ST3 status register is cleared (by default), the byte address range FE0000h – FFFFFFh is used for the on-chip ROM. When the MPNMC bit field of the ST3 status register is set through software, the on-chip ROM is disabled and not present in the memory map, and byte address range FE0000h – FFFFFFh is directed to the EMIF's external memory space on EM_CS5. A hardware reset always clears the MPNMC bit, so it is not possible to disable the ROM at reset. However, the software reset instruction does not affect the MPNMC bit. The ROM can be accessed by the CPU program and data buses.

6.2.1.4 I/O Memory

The device includes a 64K byte I/O space for the memory-mapped registers of the DSP peripherals and system registers used for idle control, status monitoring and system configuration. I/O space is separate from program and memory space and is accessed with separate instruction opcodes or via the DMA's.

Table 6-3 lists the memory-mapped registers of the device. Note that not all addresses in the 64K byte I/O space are used; these addresses should be treated as RESERVED and not accessed by the CPU nor DMA. For the expanded tables of each peripheral, see Section 6.2.4, Register Map.

Some of the DMA controllers have access to the I/O-Space memory-mapped registers of the following peripherals registers: I2C, UART, I2S, MMC and SD, EMIF, McBSP, McSPI, USB, and SAR ADC.

Before accessing any peripheral memory-mapped register, make sure the peripheral being accessed is not held in reset via the Peripheral Reset Control Register (PRCR) and its internal clock is enabled via the Peripheral Clock Gating Control Registers (PCGCR1 and PCGCR2).

6.2.2 External Memory

The external memory space of the device is located at the byte address range 050000h – FFFFFFh. The external memory space is divided into five chip select spaces: one dedicated to SDRAM and mobile SDRAM (EMIF CS0 or CS[1:0] space), and the remainder (EMIF CS2 through CS5 space) dedicated to asynchronous devices including flash. Each chip select space has a corresponding chip select pin (called EM_CSx) that is activated during an access to the chip select space.

The external memory interface (EMIF) provides the means for the DSP to access external memories and other devices including: mobile single data rate (SDR) synchronous dynamic RAM (SDRAM and mSDRAM), NOR Flash, NAND Flash, and asynchronous static RAM (SRAM). Before accessing external memory, you must configure the EMIF through its memory-mapped registers.

The EMIF provides a configurable 16- or 8-bit data bus, an address bus width of up to 21-bits, and 5 dedicated chip selects, along with memory control signals. To maximize power savings, the I/O pins of the EMIF can be operated at an independent voltage from the other I/O pins on the device.

6.2.3 Memory Map

The device provides 16M bytes of total memory space composed of on-chip RAM, on-chip ROM, and external memory space supporting a variety of memory types. The on-chip, dual-access RAM allows two accesses to a given block during the same cycle. There are 8 blocks of 8K bytes of dual-access RAM. The on-chip, single-access RAM allows one access to a given block per cycle. In addition, there are 32 blocks of 8K bytes of single-access RAM.

The remainder of the memory map is divided into five external spaces, and on-chip ROM. Each external space has a chip select decode signal (called EM_CS0, EM_CS[2:5]) that indicates an access to the selected space. The external memory interface (EMIF) supports access to asynchronous memories such as SRAM, NAND, or NOR and Flash, and mobile single data rate (mSDR) and single data rate (SDR) SDRAM.

The DSP memory is accessible by different master modules within the DSP, including the C55x CPU, the four DMA controllers, the UHPI, and the CDMA of USB (see Figure 6-1). However, only the UHPI and USB CDMA can access the SARAM.

A. Address shown represents the first byte address in each block.
B. The first 192 bytes are reserved for memory-mapped registers (MMRs).
C. Out of the four DMA controllers, only DMA controller 3 has access to the external memory space.
D. The USB controller and UHPI do not have access to DARAM.
E. The CS0 space can be accessed by CS0 only or by CS0 and CS1.

6.4.1 Invocation Sequence

The boot sequence is a process by which the device's on-chip memory is loaded with program and data sections from an external image file (in flash memory, for example). The boot sequence also allows, optionally, for some of the device's internal registers to be programmed with predetermined values. The boot sequence is started automatically after each device reset. For more details on device reset, see Section 5.7.3, Reset.

This device can boot from EMIF, UART, SPI, I2C, eMMC, MMC, SD, SDHC, UHPI, McSPI, or USB interface. For a complete description of the boot options, see Using the TMS320C5517 Bootloader [literature number SPRABP1].

The peripheral interface that the device boots from is determined by the configuration of the EM_A[20:15] or GP[26:21] pins at reset. The values of EM_A[20:15] or GP[26:21] are latched at reset into the BootMode[5:0] bits in the BootMode register (1C34h) and the Bootloader reads the bits to determine a peripheral interface for booting.

The on-chip Bootloader allows the DSP registers to be configured during the boot process, if the optional register configuration section is present in the boot image. For more information on the boot modes supported, see Section 6.4, Boot Modes.

See Figure 6-5, Boot Timing, and the notes at the bottom of the figure, for an illustration of the boot sequence.

1. Enter the boot sequence described in boot sequence Step 1.
2. The maximum wait time from reset between (1) and (2) until the reset is released is 20 ms.
3. The bootloaded code starts. The best-case time is 200 ms from the start of the boot sequence (see note 2) due to the BG_CAP settling time in Step 18. The worst-case time is the loading time for the bootloaded code when it exceeds 200 ms.
Figure 6-5 Boot Timing

The device bootloader follows the following steps:

  1. Immediately after reset, the CPU fetches the reset vector from 0xFFFF00. MP or MC is 0 by default, so 0xFFFF00 is mapped to internal ROM. The PLL is in bypass mode. The input clock is assumed to be in the range of 11.2896–19.2 MHz.
  2. Set CLKOUT slew rate control to slow slew rate.
  3. Idle all peripherals and HWA.
  4. Apply manufacturing trim to the bandgap references.
  5. Disable CLKOUT.
  6. The Bootloader configures the system clock generator based on boot mode (see Section 6.4, Boot Modes, for details on boot mode) and enables TIMER0 to count the settling time of BG_CAP. Bootloader will try this main loop infinitely if it cannot get the correct boot signature.

    7. [Main Loop]

  7. If McSPI boot, test for 24-bit McSPI flash boot on SPI_CS[0] using a clock-rate close to, but not over, 10 MHz, or a clock-rate close to, but not over, 40 MHz based on the boot mode. Set Serial Port 1 Mode on the External Bus Selection Register to 1:
    1. Check the first two bytes read from the boot table for a boot signature match using 24-bit address mode.
    2. If the boot signature is not valid, go to .
    3. Set Register Configuration, if present in boot image.
    4. Attempt McSPI Serial Memory boot and go to .
  8. If UHPI boot, the external host has to communicate in 16-bit multiplexed mode:
    Note: The bootloader sets up the UHPI slave to handshake with an external UHPI master.
    1. The external host power up the device and must wait for the settling time of BG_CAP to elapse before executing the next step.
    2. The bootloader waits for the external host to finish transferring the data.
    3. External Host writes to device on-chip memory. The code or data sections are directly loaded to the desired locations on device by the external host.
    4. External Host interrupts the device through the DSP_INT in the UHPIC register after code transfer complete.
    5. Bootloader branches to the entry point. The entry point is located in the last block of SARAM, word addresses 0x27FFA and 0x27FFB. To ensure data integrity, the external host writes two 16-bit signatures in 0x27FFC and 0x27FFD with respective values of 0x1234 and 0xABCD. If the address of the entry point is in DARAM space or incorrect signatures are detected in 0x27FFC and 0x27FFD, go to .
    6. Go to .
  9. If NOR boot, test for NOR boot on all asynchronous CS spaces (EM_CS[2:5]) with 16-bit access:
    Note: The booatloader requires NOR flash that supports a reset command (0xF0 on data).
    1. Check the first 2 bytes read from boot signature.
    2. If the boot signature is not valid, go to .
    3. Set Register Configuration, if present in boot image.
    4. Attempt NOR boot and go to .
  10. If NAND boot, test for NAND boot on all asynchronous CS spaces (EM_CS[2:5]) with 16-bit access:
    1. Check the first 2 bytes read from boot table for a boot signature match. If the boot signature is not valid, read the first 2 bytes again using 8-bit access on all asynchronous CS spaces (EM_CS[2:5])
    2. If the boot signature is still not valid, go to .
    3. Set Register Configuration, if present in boot image.
    4. Attempt NAND boot and go to .
  11. If SPI boot, test for 16- and 24-bit SPI EEPROM or Flash boot on SPI_CS[0] using a clock-rate close to, but not over, 1 MHz, or a clock-rate close to, but not over, 10 MHz based on the boot mode. Set Parallel Port Mode on the External Bus Selection Register to 5, then set to 6:
    1. Check the first 2 bytes read from boot table for a boot signature match using 16-bit address mode.
    2. If the boot signature is not valid, read the first 2 bytes again using 24-bit address mode.
    3. If the boot signature is not valid from either case (16-bit and 24-bit address modes), go to .
    4. Set Register Configuration, if present in boot image.
    5. Attempt SPI Serial Memory boot and go to .
  12. If I2C boot, test for 16-bit I2C EEPROM boot with a 7-bit slave address 0x50 and 400-kHz clock rate.
    1. Check the first 2 bytes read from boot table for a boot signature match using 16-bit address mode.
    2. If the boot signature is not valid, go to .
    3. Set Register Configuration, if present in boot image.
    4. Attempt I2C EEPROM boot and go to .
  13. If eMMC, MMC, SD, or SDHC Controller 0 boot, program SD0 and search for the filename “bootimg.bin" under the first partition’s root directory. For SD or SDHC, the device must comply with SD/SDHC specification v1.1 or v2.0 for FAT16 or FAT32 using SD or SDHC unsecure mode.
    If eMMC, the bootloader will check the boot partition for a bootable image before checking the root directory for "bootimg.bin". For eMMC or MMC, the device must comply with eMMC/MMC specification v4.3 for FAT32 using eMMC or MMC nonencrypted mode.
    1. Check the first 2 bytes read from boot table for a boot signature match.
    2. If the boot signature is not valid, go to .
    3. Set Register Configuration, if present in boot image.
    4. Attempt eMMC, MMC, SD, or SDHC boot and go to .
  14. If eMMC, MMC, SD, or SDHC Controller 1 boot, program SD1 and search for the filename “bootimg.bin" under the first partition’s root directory. For SD or SDHC, the device must comply with SD/SDHC specification v1.1 or v2.0 for FAT16 or FAT32 using SD or SDHC unsecure mode.
    If eMMC, the bootloader will check the boot partition for a bootable image before checking the root directory for "bootimg.bin". For eMMC or MMC the device must comply with eMMC/MMC specification v4.3 for FAT32 using eMMC or MMC nonencrypted mode.
    Note: Do not boot from eMMC if no valid image is present. Booting from eMMC without a valid image will put the card into an inactive state.
    1. Check the first two bytes read from boot table for a boot signature match.
    2. If the boot signature is not valid, go to .
    3. Set Register Configuration, if present in boot image.
    4. Attempt eMMC, MMC, SD, or SDHC boot and go to .
  15. If UART boot, set PLL to multiply the input clock by 3 and adjust TIMER0 for the settling time of BG_CAP. Program UART with 9600-, 57600-, or 115200-baud based on boot mode, 8-bit data, odd parity, one stop-bit, and auto flow control using CTS or RTS:
    1. Check the first 2 bytes read from boot table for a boot signature match.
    2. If the boot signature is not valid, return to the beginning of step 15.
    3. Attempt UART boot and go to .
  16. If USB boot, set PLL to multiply the input clock by 3 and adjust TIMER0 for the settling time of BG_CAP. Use USB on endpoint 1. The device has vendor-ID 0x0451 and product-ID 0x9010 and uses Bulk Endpoint 1 OUT to receive the boot image from the USB host:
    1. Check the first 2 bytes read from boot table for a boot signature match.
    2. If the boot signature is not valid, return to the beginning of step 16.
    3. Attempt USB boot and go to .
  17. If polling mode, there is a fixed order of supported boot devices on which a valid image is checked.
    • Polling Mode 1:
      1. NOR
      2. NAND
      3. SPI
      4. I2C
      5. SD/SDHC, MMC/eMMC Controller 0 (see note below)
      6. SD/SDHC, MMC/eMMC Controller 1 (see note below)
      7. UART/USB
    • Polling Mode 2:
      1. NOR
      2. NAND
      3. SPI
      4. I2C
      5. SD/SDHC, MMC/eMMC Controller 0 (see note below)
      6. McSPI
      7. UART/USB

    18. The first device with a valid boot image is used to load and execute user code. If none of these devices has a valid boot image, the bootloader modifies the CPU clock setup as follows:

    • If CLK_SEL=0, the bootloader powers up the PLL and sets its frequency to 36 MHz (12 MHz multiplied by 3).
    • If CLK_SEL=1, the bootloader powers up the PLL and sets it to multiply CLKIN by 3.

    This change in the CPU clock setup is required to meet the minimum frequency needed by the USB module. After the CPU clock setup changes, the bootloader enters an endless loop and checks for data received on the UART/USB. If a valid boot image is received, the image is used to load and execute user code. If no valid boot image is received, the bootloader continues to monitor the boot devices. If the time since the trim setup exceeds 200 ms during this endless loop, the bootloader re-enables the low-voltage detection circuit to ensure the circuit is not disabled for an extended period.

    Note: If MMCx_CMD is low, the bootloader continues to check for a valid boot image in the card controller. MMCx_CMD must be high or toggle in order to move from the card controller to the next peripheral for a valid boot image.

  18. If the boot signature is not valid, toggle XF when the retry count reaches 100.
  19. Copy the boot image sections to system memory. Then set the XF port low to indicate that boot-up is complete. Ensure the settling time of BG_CAP has elapsed since step 6 before proceeding to execute the bootloaded code.
  20. Jump to the specified entry point.

6.4.2 DSP Resources Used By the Bootloader

The Bootloader uses SARAM block 31 for the storing of temporary data. This block of memory is reserved during the boot process. However, after the boot process is complete, it can be used by the user application.
