摘要
为解决反馈型两级交换结构(FTSA)对调度算法的时间限制问题,提出了一种脉动反馈型两级交换结构(PFTSA). PFTSA将调度算法所需信息以脉动的形式反馈至输入端口,通过预处理机制使调度算法获得目标缓存的准确信息,从而避免信元冲突和信元失序.相对于现有方案,PFTSA简化了交换结构和交换流程,同时提高了时延性能.
To solve the time constraint of scheduling algorithm in the feedback-based two-stage switch architecture(FTSA),a new scheme called pulsating feedback-based two-stage switch architecture(PFTSA)is proposed,which transmits the required information back to the input port in a way of pulsating.The accurate data of target buffers can be obtained by the scheduling algorithm with a preprocessing scheme,so as to avoiding the cell conflicting and disordering.As compared to the existing schemes,PFTSA can not only simplify the switch architecture and procedure,but also improve the delay performance.
