PSA for DWDB

PSA for DWDB can be used to ensure the integrity of written data. If it is required to compute the PSA for a set of memory locations (which is required to periodically check the integrity of configuration registers, static memory content, and so forth), it needs to be first read to the CLA and then written to a dummy location. PSA for DWDB allows the polynomial to be configured using MPSACTL.MPSA2CFG configuration.

  • 00 – PSA (1 + x + x2 + x22 + x32)
  • 01 – CRC32 (1 + x + x2 + x4 + x5 + x7 + x8 + x10 + x11 + x12 + x16 + x22 + x23 + x26 + x32)
