Abstract
Multi-processor systems and methods are disclosed that employ speculative source requests to obtain speculative data fills in response to a cache miss. In one embodiment, a source processor generates a speculative source request and a system source request in response to a cache miss. At least one processor provides a speculative data fill to a source processor in response to the speculative source request. The processor system provides a coherent data fill to the processor in response to the system source request.
