Abstract
A processor and methods of detecting a corrupted instruction stream within a processor include executing, by the processor, a program including a plurality of basic blocks, each of which includes a sequence of instructions to be executed by the processor without branching. The method includes implicitly initializing a first cyclic-redundancy-check (CRC) generator based on a first portion of an address of a first instruction in a first basic block and a second CRC generator based on a second portion of the address of the first instruction, generating, by the first CRC generator, a first CRC output according to a first polynomial and, by the second CRC generator, a second CRC output according to a second polynomial, and when an end of the first basic block is reached without encountering an instruction to transfer control from a first function to a second function, selectively deferring a CRC check operation.
