一种基于TMS320C6678的JPEG编码算法并行实现方法

摘要

Aimming at the real-time requirement of the digital video bus in equipment application, based on the analysis of JPEG encoding and parallel task in multicore DSP, it proposes a method of JPEG encoding algorithm parallel implementation based on TMS320C6678, the method implements task-level parallel pipeline and efficient inter-core communication. Experimental results show that the method is feasible and effective, and the real-time processing capability of JPEG encoding system based on TMS320C6678 has improved so much.%针对数字视频总线在装备应用中的实时性需求,在分析JPEG编码原理和多核DSP任务并行的基础上,提出了一种基于TMS320C6678的JPEG编码算法并行实现方法,该方法实现了任务级并行流水和核间高效通信.实验结果表明,该方法是可行、有效的,并且基于TMS320C6678的JPEG编码系统的实时处理能力有很大提升.
