MCRC Controller is a module which is used to perform CRC (Cyclic Redundancy Check) to verify the integrity of memory system. A signature representing the contents of the memory is obtained when the contents of the memory are read into MCRC Controller. The responsibility of MCRC controller is to calculate the signature for a set of data and then compare the calculated signature value against a pre-determined good signature value. MCRC controller provides up to four channels to perform CRC calculation on multiple memories in parallel and can be used on any memory system. Channel 1 can also be put into data trace mode. In data trace mode, MCRC controller compresses each data being read through the CPU read data bus.
When using the MCRC module in PSA mode while ECC is enabled, bus masters (e.g. FTU, HTU, DMA or CPU) should not write to the data RAM (TCRAM) to avoid corrupting the PSA value.
