Latest Patents

Edenfield's latest patents include a data processor designed for reloading deferred pushes in a copy-back data cache. This innovative data processor addresses the challenges that arise during cache 'miss' events. When such an event occurs, the cache controller selects a cache line for replacement and requests a burst line read to transfer the necessary cache line from external memory. If the data entries in the selected cache line are marked dirty, the cache controller pushes the cache line or its dirty portions into a buffer. This buffer temporarily stores the cache line until the completion of the burst line read. In cases where the burst line read terminates abnormally, the data cache controller reloads the copy-back cache with the cache line stored in the buffer. This process effectively avoids multiple concurrent exception conditions and prevents the unnecessary removal of valid cache entries.

Another significant patent by Edenfield involves a data processing system that utilizes a block move instruction for burst transfers. This block MOVE instruction allows programmers to issue commands to a loosely coupled system bus controller. It facilitates memory-to-memory moves of multiple data entries using burst mode transfers for both reads and writes. This instruction enables programmers to maximize the bus bandwidth of the system bus for various data transfers, including direct memory access (DMA), block moves, and memory page initialization.
