摘要
数字信号处理器(DSP)是对数字信号进行高速处理的专用芯片。单核结构的DSP已经不能满足信息行业发展的需求,多核结构DSP应运而生,同时,也为如何准确高效地利用多核处理器平台设计并行软件带来了挑战。文中主要基于德州仪器TMS320C6678平台,对多核DSP应用开发进行研究,并简单介绍了基于此DSP的AVS视频双核并行解码的实现。
Digital signal processor （DSP） is a special chip for high speed processing of digital signal. Single-core DSP has been unable to meet the needs of the development of the information technology. So, muhicore DSP was proposed, while bringing a challenge for accurate and efficient use of concurrent software design based on multicore DSP. This article researched on muhicore DSP produced by TI TMS320C6678, and proposed the achievement of AVS video dual-core decode based on the DSP.
