【 摘 要 】

References(20)Recent increases in the type and amount of multimedia data has required a versatile device enough to play various data. Especially a variety of lossless compression algorithms often causes large amount of redundant computations. In this paper, an application-specific instruction processor tailored to effectively process such coding algorithms is proposed. The functionality and performance of the processor has been verified by using it to run the H.264/AVC baseline profile encoder. The experimental results show that the proposed processor can save about 96% and 36% of the execution cycles of ARM Cortex-A9 and Intel i7 processors, respectively.
