Abstract:
A processor generates a signature value indicating a sequence of executed instructions, and the signature value is compared to signature values calculated for two or more possible sequences of executed instructions to determine which instruction sequence was executed. The signature is generated via a signature generator during program execution, and is provided external to the processor via a signature message.
