The DMPAC implements several internal diagnostic features:
The external host (software) driven reset to DMPAC is the only guaranteed way of recovering from an error (due to any source).
If the input data and configuration to DMPAC operation is pre-determined (used for periodic testing), then output data also gets known. In such a situation, complete output buffer comparison can be avoided by enabling PSA on output buffer. The PSA generates a 32-bit CRC value which can be compared to a pre-calculated value, thus avoiding complete output buffer comparison. The DOF and SDE cores implement PSA internal to them.
