Latest Patents

One of his latest patents is for a "Tagged token data processing system with operand matching in activation." This invention describes a data flow processing system that includes multiple processing elements and memory units. Communication among these elements is facilitated by an interconnection network, allowing for efficient data processing. The system operates on data objects called tokens, which initiate activities within the processing element pipelines. The patent also details how operands for instructions are matched in non-associative memory portions known as activation frames, which have a state field indicating the presence of values and other information.

Another significant patent is for "Integrated scalar and vector processors with vector addressing." This invention closely integrates a vector processor with a scalar processor, enabling virtual-to-physical memory translation for both scalar and vector operations. The scalar processor intercepts block move operations, converting write commands to read commands, thus enhancing data handling efficiency. The patent outlines the use of prefetch queues and write queues between main memory and the vector processor, along with support for a microinstruction interface.
