    摘要: A trace management architecture to enable the reuse of uops within one or more repeated traces. More particularly, embodiments of the invention relate to a technique to prevent multiple accesses to various functional units within a trace management architecture by reusing traces or sequences of traces that are repeated during a period of operation of the microprocessor, avoiding performance gaps due to multiple trace cache accesses and increasing the rate at which uops can be executed within a processor.

    摘要: A method and apparatus for monitor and mwait in a distributed cache architecture is disclosed. One embodiment includes an execution thread sending a MONITOR request for an address to a portion of a distributed cache that stores the data corresponding to that address. At the distributed cache portion the MONITOR request and an associated speculative state is recorded locally for the execution thread. The execution thread then issues an MWAIT instruction for the address. At the distributed cache portion the MWAIT and an associated wait-to-trigger state are recorded for the execution thread. When a write request matching the address is received at the distributed cache portion, a monitor-wake event is then sent to the execution thread and the associated monitor state at the distributed cache portion for that execution thread can be reset to idle.

    摘要: A platform may comprise a core coherency domain, graphics coherency domain and a non-coherent domain. A graphics acceleration unit (GAU) of the graphics coherency domain may generate data units from an application and the data units may comprise display data units. The GAU may annotate the display data units with an annotation value before flushing the display data units to an on-die cache. The GAU may identify modified display data units among the display data units stored in the on-die cache and issue flush commands to cause flushing of the modified display data units from the on-die cache to a main memory. The display engine of the non-coherent domain may use the modified display data units stored in the main memory to render a display on a display device.
