Richard D Freeman is a notable inventor based in Mission Viejo, CA (US). He has made significant contributions to the field of microcode processing systems, holding a total of 3 patents. His work focuses on enhancing the efficiency and speed of processing systems through innovative designs.

Latest Patents

One of his latest patents is a "Single chip processing system utilizing general cache and microcode." This invention features a microcode cache memory on a processor chip that supplies frequently used microcode instruction words to the processor. A bank of multiple Tag-Status RAMs holds addresses of microcode words residing in a bank of Data RAMs. A state machine and a special Least Recently Used Random Access Memory (LRU RAM) work together to maintain the more frequently used words in the Data RAMs, allowing for more hits and providing the requested word in one clock cycle. Additionally, a 90-bit microcode word with 20 fields enables the processor to perform multiple functions simultaneously in parallel.

Another significant patent is the "Single chip processing unit providing immediate availability of." This invention includes a multi-cache memory system that resides on-chip with a system interface to external memory. A general cache memory holds frequently used data and OPCODES for delivery to a processor in one clock cycle. The microcode cache also holds frequently used microcode instruction words for quick access. Both cache memories operate to replace less frequently used OPCODES, data words, and microcode instruction words with more frequently used ones.
