Latest Patents

David Archer holds a patent for a "Processor system with writeback cache using writeback and non-writeback." This invention describes a pipelined CPU that executes instructions of variable length while referencing memory using various data widths. The system employs a writeback cache in a hierarchical cache arrangement, allowing writeback to proceed even when other accesses are suppressed due to full queues. The design includes separate queues for return data from memory and cache invalidates, maintaining the order of bus transactions through a pointer arrangement. The bus protocol utilized by the CPU for communication with the system bus is of the pended type, with transactions identified by an ID field that specifies the originator, while arbitration for bus grants occurs simultaneously with address/data transactions.
