Data processing system, processor and method of data processing in which local memory access requests are serviced by state machines with differing functionality |
摘要 |
A data processing system includes a local processor core and a cache memory coupled to the local processor core. The cache memory includes a data array, a directory of contents of the data array, at least one snoop machine that services memory access requests of a remote processor core, and multiple state machines that service memory access requests of the local processor core. The multiple state machines include a first state machine that has a first set of memory access requests of the local processor core that it is capable of servicing and a second state machine that has a different second set of memory access requests of the local processor core that it is capable of servicing.
