摘要: An instruction, corresponding methods, and circuitry for efficiently performing partial dot sum products are provided. The instruction may include a source select field for specifying one or more source word elements to participate in the dot sum operation. The instruction may also include a target select field for specifying one or more (or none) target word elements for storing the result of the dot sum operation.

摘要: Computer systems with direct updating of cache (e.g., primary L1 cache) memories of a processor, such as a central processing unit (CPU) or graphics processing unit (GPU). Special addresses are reserved for high speed memory. Memory access requests involving these reserved addresses are routed directly to the high speed memory. Memory access requests not involving these reserved addresses are routed to memory external to the processor.
