Abstract
A data processing system includes a processor, a memory system, a cache controller and a cache accessible by the processor via the cache controller. The cache controller provides an asynchronous interface between the processor and the memory system. Instructions, issued by the processor to the cache controller, are completed by the cache controller without blocking the processor. In addition, the cache controller tracks a completion status of the memory operation associated with each instruction and enables the completion status to be queried by the processor. Status of the memory operation may be recorded as an entry in a log, where the log, or a property of the log, is accessible by the processor.
