User's Guides
SPRUG82TMS320C674x DSP Cache User's Guide. Explains the fundamentals of memory caches and describes how the two-level cache-based internal memory architecture in the TMS320C674x digital signal processor (DSP) can be efficiently used in DSP applications. Shows how to maintain coherence with external memory, how to use DMA to reduce memory latencies, and how to optimize your code to improve cache efficiency. The internal memory architecture in the C674x DSP is organized in a two-level hierarchy consisting of a dedicated program cache (L1P) and a dedicated data cache (L1D) on the first level. Accesses by the CPU to the these first level caches can complete without CPU pipeline stalls. If the data requested by the CPU is not contained in cache, it is fetched from the next lower memory level, L2 or external memory.
SPRUFE8TMS320C674x DSP CPU and Instruction Set Reference Guide. Describes the CPU architecture, pipeline, instruction set, and interrupts for the TMS320C674x digital signal processors (DSPs). The C674x DSP is an enhancement of the C64x+ and C67x+ DSPs with added functionality and an expanded instruction set.
SPRUFK5TMS320C674x DSP Megamodule Reference Guide. Describes the TMS320C674x digital signal processor (DSP) megamodule. Included is a discussion on the internal direct memory access (IDMA) controller, the interrupt controller, the power-down controller, memory protection, bandwidth management, and the memory and cache.
SPRUFK9TMS320C674x/OMAP-L1x Processor Peripherals Overview Reference Guide. Provides an overview and briefly describes the peripherals available on the device.
SPRUGM5TMS320C6742 DSP System Reference Guide. Describes the System-on-Chip (SoC) system. The SoC system includes TI’s standard TMS320C674x Megamodule and several blocks of internal memory (L1P, L1D, and L2).
