Latest Patents

One of Moulton's latest patents is titled "Superscaler instruction pipeline having boundary identification logic." This innovative mechanism manages variable length instructions in cache and is comprised of three cooperating elements designed to optimize self-modifying code. It anticipates the next instructions for branch operand management. A content addressable memory (CAM) stores 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. 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 minimizes the circuitry necessary for fetches across cache lines and is loaded with sequentially anticipated prefetched instructions from the cache. These anticipated instructions can then be concatenated by a fetch aligner.
