Register error detection system

Abstract

A system for register error detection is described, the system comprising: a plurality of addressable registers comprising sets of registers, the registers in each set having contiguous addresses; a cyclic redundancy check generator coupled to the addressable registers and configured to determine a cyclic-redundancy-check result for each set of registers from the values of each of the respective set of registers; a controller coupled to the registers and the cyclic-redundancy-check generator. The controller comprises a cyclic-redundancy-check calculator and is configured to determine an expected cyclic-redundancy-check result from expected values for each of the set of registers, to read the cyclic-redundancy-check result for each of the set of registers determined by the cyclic-redundancy-check generator, and to compare the generated cyclic-redundancy-check result with the calculated cyclic-redundancy-check result and wherein a difference between the generated cyclic-redundancy-check result and the calculated cyclic-redundancy-check result is indicative of an error condition.
