On Implementation of Media Processors

چکیده
Conventional standard processors do not correspond well to these characteristics of MSP algorithms. Therefore, special architectural approaches are necessary for multimedia processors to deliver the required high processing power with efficient use of hardware resources. Function-specific ASICs dedicated to particular MSP subtasks can typically achieve highest performance levels at minimum cost for silicon area and optimized power consumption. However, they lack the flexibility to accommodate to algorithm modifications, and the large design effort justifies a dedicated implementation only for high-volume consumer market products of fixed functionality. Alternatively, programmable approaches offer a higher degree of flexibility. In order to attain MSP performance, architectural strategies for programmable processors are based on parallelization and adaptation principles. Several alternatives exist to exploit the parallelization potential of MSP algorithms for programmable architectures:
