Analyzing the Performance of Multimedia Applications in Pentium Processors

Abstract

This paper presents the study and results of running four core multimedia applications on Pentium IV architecture with and without HTT support. The proposed approach is based on three main steps: first step is to analyze the theoretical concepts. The second step is to verify the concepts by considering various multimedia applications. The third step is to propose a new technique. Based on the analysis, the two observations were made. a) Irrespective of the image format (JPG, BMP or GIF), processor with HTT support increase the speed of the processor. b) Including the threading concept enhances the speed of the processor. So an attempt is made to propose new technique, which makes use of threading concept. 1.Introduction.Processor performance has long been defined in terms of clock speeds: Performance Metrics is defined by units Response time, Throughput and Utilization. Hyper-Threading Technology enables gaming enthusiasts to play the latest titles and experience ultra realistic effects and game play. A salient feature of Pentium is its super scalar, super pipelined architecture. Intel introduced the MMX (Multimedia Extension) technology at a time when there was a tremendous need to improve the 2-D and 3-D imaging for multimedia applications. Intel provides around 57 MMX instructions, which helps the programmer to write efficient programs for image filtering, image enhancement, coding and other algorithms. Hyper-Threading Technology allows one processor to work on two separate operations at the same time rather than one at a time. Intel® Advanced Digital Media Boost is a feature that significantly improves performance when executing Streaming SIMD Extension
