【摘要】:多核时代处理器内核间的通信是多处理系统所面临的主要难题.通过研究现有的分布式与共享式通信方式,提出了一种采用分布式交点队列(crosspiont-queued,CQ)结构代替传统的共享通信结构,并利用中断机制实现握手的思路,设计了一种交点队列型多核DSP核间通信结构.并构建了一种共享式与分布式混合的DSP系统,将两种结构进行了性能对比,测试结果显示,此结构通信效率优于共享式,尤其大数据量时优势明显.
[Abstract]:Communication between processor cores in multi-core era is a major problem faced by multi-processing systems. Based on the study of the existing distributed and shared communication methods, this paper proposes a new method to replace the traditional shared communication structure by using the distributed crossover crosspiont-queued CQQ structure, and the idea of handshaking is realized by using the interrupt mechanism. A multi-core DSP core communication structure with intersection queue is designed. A shared and distributed hybrid DSP system is constructed, and the performance of the two structures is compared. The test results show that the communication efficiency of the structure is better than that of the shared one, especially when the data is large.
