METHODS AND APPARATUS FOR REDUCING COMMAND PROCESSING LATENCY WHILE MAINTAINING COHERENCE |
摘要 |
In a first aspect, a first method of reducing command processing latency while maintaining memory coherence is provided. The first method includes the steps of (1) providing a memory map including memory addresses available to a system; and (2) arranging the memory addresses into a plurality of groups. At least one of the groups does not require the system, in response to a command that requires access to a memory address in the group from a bus unit, to get permission from all remaining bus units included in the system to maintain memory coherence. Numerous other aspects are provided.
