L2RAMW is the TMS570 level two RAM wrapper. Major features implemented in this device include:
- Supports 512KB of L2 SRAMs
- One 64-bit OCP interface
- Built-in ECC generation and evaluation logic
- The ECC logic is enabled by default.
- When enabled, automatic ECC correction on write data from masters on any write sizes (8-,16-,32-,or 64-bit)
- Less than 64-bit write forces built in read-modify-write
- When enabled, reads due to read-modify-write go through ECC correction before data merging with the incoming write data
- Redundant address decoding. Same address decode logic block is duplicated and compared to each other
- Data Trace
- Support tracing of both read and write accesses through RTP module
- Auto initialization of memory banks to known values for both data and their corresponding ECC checksum
