19.4.2. Local Memory Buffer
- The write FIFO buffer is a 128 × 32-bit memory (512 total bytes)
- The read FIFO buffer is a 32 × 32-bit memory (128 total bytes)
- The ECC buffer is a 96 × 16-bit memory (1536 total bytes)
The SPRAM is a 8192 x 35-bit (32 data bits and 3 control bits) memory and includes support for ECC (Error Checking and Correction). The ECC block is integrated around a memory wrapper. It provides outputs to notify the system manager when single-bit correctable errors are detected (and corrected) and when double-bit uncorrectable errors are detected. The ECC logic also allows the injection of single- and double-bit errors for test purposes. The ECC feature is disabled by default. It must be initialized to enable the ECC function.
