Title: David W. Clift: Innovator in Processor Technology
Introduction
David W. Clift is a notable inventor based in Hillsboro, OR (US). He has made significant contributions to the field of processor technology, holding a total of 6 patents. His work focuses on enhancing the performance and reliability of processors, particularly in handling speculative data and code transitions.
Latest Patents
One of Clift's latest patents is titled "Processor with registers storing committed/speculative data and a RAT state history recovery mechanism with retire pointer." This invention provides a mechanism for processors to recover from failures in predicted instruction paths, such as mispredicted branches. The design includes multiple physical registers that can store either architectural or speculative data, along with a primary array that maps logical registers to physical registers. Additionally, a history buffer is utilized to store historical mappings, allowing the processor to revert to a stable state when a failure is detected.
Another significant patent is "Performance enhancement for code transitions of floating point and packed data modes." This technique introduces a tag incorrect (TINC) bit that indicates potential fault conditions during mode transitions. By using the TINC bit, the system can prevent fault generation when the tags of floating point or packed data registers do not meet expected values.
