This report presents an in-depth performance characterization of a variety of processors released over the last decade. The processors considered include Intel and PowerPC and vary widely with respect to architectural design parameters. The benchmark experiments utilize applications from two different classes of codes. The first class, consisting of synthetic benchmarks, includes the popular Dhrystone and Whetstone suites. The second class includes a set of widely used Image Processing IP kernels. Following the presentation of the results from these experiments, a set of techniques for performance prediction is given based on linear correlation. This report provides an evaluation of the effectiveness of these techniques. The results show that when processors are categorized by microarchitectural families and certain restrictions to input size are employed, linear correlation shows promise for being an effective performance predictor for the IP kernels.
