【摘要】：多核時代處理器內(nèi)核間的通信是多處理系統(tǒng)所面臨的主要難題.通過研究現(xiàn)有的分布式與共享式通信方式,提出了一種采用分布式交點隊列(crosspiont-queued,CQ)結(jié)構(gòu)代替?zhèn)鹘y(tǒng)的共享通信結(jié)構(gòu),并利用中斷機制實現(xiàn)握手的思路,設(shè)計了一種交點隊列型多核DSP核間通信結(jié)構(gòu).并構(gòu)建了一種共享式與分布式混合的DSP系統(tǒng),將兩種結(jié)構(gòu)進(jìn)行了性能對比,測試結(jié)果顯示,此結(jié)構(gòu)通信效率優(yōu)于共享式,尤其大數(shù)據(jù)量時優(yōu)勢明顯.
[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.
