Abstract: A system with multiple processing domains sharing a memory resource accessed via a shared memory controller detects a memory error. As data is written to the shared memory resource, each processing domain generates a diagnostic code as a function of the data, the memory address for the data, and of a unique identifier corresponding to the processing domain. The diagnostic code is stored with the data for verification when the data is read back. As the data is read back, the processing domain separates the diagnostic code from the data being read and generates another diagnostic code in the same manner as the original diagnostic code. The other diagnostic code is compared to the initial diagnostic code. If both diagnostic codes are the same, the processing domain can be confident that the data read from the shared memory resource is the same as the data that was originally written.

Abstract: Various embodiments of the invention relate to continuously verifying semiconductor device state integrity. A counter is combined to form part of the Cyclic Redundancy Check (CRC) calculation for control register within the semiconductor device. The counter is initialized to zero and resets after a predetermined number of cycles. The counter value is added to the currently calculated CRC value to get a combined CRC value. Every time a CRC value is calculated for the register bank, the counter value is updated, e.g. incremented. If the CRC calculation is repeated enough times, the counter value will reach its maximum value, and then roll over to its initial value of zero. If no errors occur in the register bank, the combined CRC value at the rolling over point will match an initial combined CRC value. Such a repetitive pattern of the combined CRC value may be used to continuously monitor control register integrity.
