摘要： 传统接口互联协议由于复杂的路由结构,使得传输效率较低。为此,提出一种分层的点对点串行传输接口协议。采用分层架构提升灵活性和可扩展性,在硬件上实现循环冗余校验,从而提升传输可靠性,选取串行传输模块减小芯片面积并提升传输效率。实验结果表明,与PCI-Express和SRIO相比,该协议接口面积小、有效带宽高、传输延时低。

Abstract: Complex routing architecture in traditional chip-to-chip interconnect protocols always result in low operating frequency.Therefore,this paper proposes a multi-layer point-to-point serial interconnect protocol.The protocol employs layered architecture to improve the flexibility and scalability,cyclic redundancy check implemented in hardware to enhance reliability,and serial transmission module to reduce the area penalty and improve efficiency.Compared with PCI-Express and SRIO,experimental results show that the protocol has the features of low area,high bandwidth and low latency.

Key words: chip-to-chip interconnection, point-to-point structure, low latency, high bandwidth, Field Programmable Gate Array(FPGA)
