As contemporary microprocessor design attempt to expose additional instruction level parallelism (ILP), data value speculation has become a mainstream microarchitectural feature. Many different value speculation techniques have been proposed. The goals are to both achieve a high prediction rate, while predicting values for critical instructions. One key issue is how value-based speculation affects other prediction mechanisms present in the pipeline. This paper investigates the impact of load… CONTINUE READING
