摘要： A method of operating a multi-level memory hierarchy of a computer system and apparatus embodying the method, wherein instructions issue having an explicit prefetch request directly from an instruction sequence unit to a prefetch unit of the processing unit. The invention applies to values that are either operand data or instructions. These prefetch requests can be demand load requests, where the processing unit will need the operand data or instructions, or speculative load requests, where the processing unit may or may not need the operand data or instructions, but a branch prediction or stream association predicts that they might be needed. Further branch predictions or stream associations that were made based on an earlier speculative choice are linked by using a tag pool which assigns a bit fields in the tag pool entries to the level of speculation depth. Each entry shares in common the bit field values associated with earlier branches or stream associations. When a branch or stream predicted entry is no longer needed, that entry can be cancelled and all entries that were to be loaded dependent on that entry can likewise be cancelled by walking through all entries sharing the bit fields corresponding to the speculation depth of the cancelled entry and tagging those entries as invalid.

摘要： A method of operating a multi-level memory hierarchy of a computer system and apparatus embodying the method, wherein instructions issue having an explicit prefetch request directly from an instruction sequence unit to a prefetch unit of the processing unit. The invention applies to values that are either operand data or instructions. In a preferred embodiment, two prefetch units are used, the first prefetch unit being hardware independent and dynamically monitoring one or more active streams associated with operations carried out by a core of the processing unit, and the second prefetch unit being aware of the lower level storage subsystem and sending with the prefetch request an indication that a prefetch value is to be loaded into a lower level cache of the processing unit. These prefetch requests can be demand load requests, where the processing unit will need the operand data or instructions, or speculative load requests, where the processing unit may or may not need the operand data or instructions, but a branch prediction or stream association predicts that they might be needed. After a predetermined number of cycles has elapsed, the speculative load request is cancelled if the request has not already been completed.

摘要： A method of maintaining cache coherency, by designating one cache that owns a line as a highest point of coherency (HPC) for a particular memory block, and sending a snoop response from the cache indicating that it is currently the HPC for the memory block and can service a request. The designation may be performed in response to a particular coherency state assigned to the cache line, or based on the setting of a coherency token bit for the cache line. The processing units may be grouped into clusters, while the memory is distributed using memory arrays associated with respective clusters. One memory array is designated as the lowest point of coherency (LPC) for the memory block (i.e., a fixed assignment) while the cache designated as the HPC is dynamic (i.e., changes as different caches gain ownership of the line). An acknowledgement snoop response is sent from the LPC memory array, and a combined response is returned to the requesting device which gives priority to the HPC snoop response over the LPC snoop response.
