Latest Patents
One of his notable patents is the "Superscaler instruction pipeline having boundary identification logic." This invention introduces a mechanism that manages variable length instructions in cache. It consists of three cooperating elements designed to optimize self-modifying code and anticipate the next instructions for branch operand management. A content addressable memory (CAM) is utilized to store addresses of lines that have been accessed for instruction fetching. In systems with a modifiable instruction stream, when the CAM matches, the system must retire certain instructions, flush instructions, and then fetch the modified instruction stream. The boundary identification logic examines a field in each cache byte to determine the nature of the byte. This field is initially cleared when the cache line is loaded and filled with the line that is fetched. An anticipation buffer is designed to minimize the circuitry necessary for fetches across cache lines, loading sequentially anticipated prefetched instructions from the cache. These anticipated instructions can then be concatenated by a fetch aligner.
