Abstract: A return stack buffer mechanism that uses two separate return stack buffers is disclosed. The first return stack buffer is the Speculative Return Stack Buffer. The Speculative Return Stack Buffer is updated using speculatively fetched instructions. Thus, the Speculative Return Stack Buffer may become corrupted when incorrect instructions are fetched. The second return stack buffer is the Actual Return Stack Buffer. The Actual Return Stack Buffer is updated using information from fully executed branch instructions. When a branch misprediction causes a pipeline flush, the contents of the Actual Return Stack Buffer is copied into the Speculative Return Stack Buffer to correct any corrupted information.

Abstract: A content addressable memory (CAM) comprising an array of CAM cells is disclosed. Each CAM cell includes a memory cell and a compare circuit that writes the memory cell from the bit lines if the word line is active and that compares memory cell data with an input data bit on the bit lines if the word line is inactive.
