This paper explores an alternative to predicting prefetch addresses, namely precomputing them. The future thread executes instructions when the primary thread is limited by resource availability. Camera Cherish every photo you take because the 5 MP primary camera in this Tab lets you click pictures in HDR giving you the best quality in every pixel while the secondary 0.3 MP camera lets you video chat with your loved one with no hassle. For the SpecInt95 benchmarks, our experiment shows that the integrated approach significantly out-performs either computation reuse or value prediction alone. These processors offer the … Customized processors use compiler analysis and design automation techniques to take a generalized architectural model and create a specific instance of it which is optimized to a given application or set of applications.
This paper introduces a hardware predictor of instruction criticality and uses it to improve performance. Front Facing Speakers Designed to deliver the ultimate true stereo sound experience, the Xolo Tab is crafted with dual speakers on the front for a ground breaking audio output. These processors offer the promise of satisfying the high performance needs of the embedded community while simultaneously shrinking design times.
But current applications with irregular … Data cache misses reduce the performance of wide-issue processors by stalling the data supply to the processor. Permitting speculative threads to directly spawn additional speculative threads reduces the overhead associated with spawning threads and enables significantly more aggressive speculation, overcoming this limitation. They are used for branch prediction, cache replacement policies, and confidence estimation and accuracy counters for a variety of optimizations. In this paper, we present a framework for automated design of small FSM predictors for customized processors. This represents two system configurations that are relatively close to each other in the design space; performance differences become even more pronounced for designs further apart. Prefetching data by predicting the miss address is one way to tolerate the cache miss latencies. Instruction cost can be naturally expressed through the critical path: if we could predict it at run-time, egalitarian policies could be replaced with cost-sensitive strategies that will grow increasingly effective as processors become more parallel.
