Embodiment Construction
[0013] This disclosure relates to providing techniques for asynchronous memory copy and cache management.
[0014] Many modern processors run at high clock speeds, which means that even slight delays in processing can result in significant lost cycles and performance degradation. For example, a processor capable of executing 10 billion instructions per second can execute 10 instructions in the 1 nanosecond it spends waiting for a blocking operation to complete. In many cases, memory copy operations can be relatively slow operations compared to the speed of the processor. During a copy operation, if the processor is engaged in a load-store operation for copying, the processor cannot perform other work. In the case of large amounts of data copying, potentially useful processor cycles may be wasted while the processor waits for the copy to complete. If such copy operations are frequent, the efficiency of the processor can be hindered by a few percent or more.
