Abstract
A processor includes a shift overflow detector for rapidly detecting overflows that may result during execution of a shift instruction. Shift indication signals are generated in response to changes in logic state between adjacent pairs of bits of a received shift data word. A received shift amount is decoded to produce decoded shift signals that indicate an amount of shifting for the received shift data word. An overflow condition is detected in response to the generated shift indication signals and the decoded shift signals and an indication of the detected overflow condition is provided.
