Abstract :
In this paper, we present a modified implementation of the Sparc R V8 architecture with multimedia oriented instructions. The purpose of the global project is to improve video compression performances without designing a dedicated co-processor or using an expensive system on chip. In this project we investigate the complexity of modifying a standard processor. We implemented 12 new instructions and use some of them to optimize an algorithm of `Sum of Absolute Difference´. The result was a performance increase by 70% in the execution of this algorithm, allowing us to expect 30% speedup in the execution of a MPEG video compression. The area increase of the integer unit is about 18% and the clock frequency is not significantly modified in a LEON-2 implementing 5 from 12 of the new instructions
