| Abstract | Value Prediction (VP) is a relatively recent developed processing technique. Its main aim is to early predict the instructions’ results, during their fetch or decode pipeline stages, and, therefore, to speculatively execute the instruction flow. The predicted value can then be used as an input to some subsequent dependent instructions so that they can execute earlier. If the prediction is incorrect, recovery mechanism must be employed to squash speculative results and re-execute all instructions that used the incorrectly predicted values. Through this paper we briefly presented this emergent paradigm and we investigated the value locality degree present in real-world programs, and extended the value locality and prediction concepts to all general-purpose registers (MIPS architecture). As a consequence, the encouraging obtained results facilitates implementation of much simpler prediction structures, significantly reducing the hardware cost and complexity. |
