Abstract
Data stream touch instructions are software-directed asynchronous prefetch instructions that can improve the performance of a system. Ideally, such instructions are used in perfect synchronization with the actual memory fetches that are trying to speed up. In practical situations, it is difficult to predict ahead of time all side effects of these instructions and memory access latency/throughput during execution of any large program. Incorrect usage of such instructions can cause degraded performance of the system. Thus, it is advantageous to measure the performance of such instructions.
