Performance improvement for H.264 video encoding using ILP embedded processor

Summary, in English

In this paper, we examine the impact of instruction level parallelism (ILP) on the full H.264 video encoding application and give quantitative performance measures of a superscalar architecture. Most research efforts have concentrated on the data intensive parts, such as kernels but these are taking less time from the entire execution as encoders are using new, more efficient algorithms. This important fact cannot be neglected since new video encoding standards have been proposed and the amount of other than data intensive computations has increased significantly. We observed significant improvement for the entire application when using superscalar architecture with out-of-order execution scheme. Tradeoffs in superscalar performance are also evaluated with combinations of measurements from simplescalar simulator
