Memory co-processor for a multi-tasking system

摘要: A co-processor (also called “memory co-processor”) provides an interface to a memory, by executing instructions on data held in the memory. The uses specified address fetch from performs instruction (such as incrementing counter or policing) obtain modified data, and writes back memory at same address. Depending embodiment, may include first buffer for holding that be received back, successive clock cycles. Instead of addition buffer, second written In some embodiments, also receives (and maintains local storage) identity task generates instruction, so cask awakened after has been executed.
