中文摘要：
针对传统片上网络中的通信通道功耗大、吞吐量低的缺点,提出一种用于片上网络的高速低功耗多轨协议异步通信通道,其具有检测完成自恢复的功能。每一级通道单元通过自动检测输出端的信号控制电路正常工作,加入门限门使整个通道单元延时不敏感,低延迟传输模块使前向传输延迟减少为1.5倍门延迟,1/4码的编码方式使电路功耗大大降低。在不同工艺模型和不同温度下对电路的性能和功耗进行仿真测试,结果表明,该通道单元最快可以在2.64GHz的频率下工作,平均动态功耗为1.252mW,可以满足高速低功耗的片上网络应用。
英文摘要：
This paper proposes a novel multi-rail asynchronous communication channel for network on chips. With throughput and threshold gate the function of self-resetting completion detection, it improves the shortcomings of low high power consumption in conventional communication channels. The application of makes the channel element delay-insensitive. Meanwhile, by the control of automatically detecting signals of the output, the circuit can work properly. The forward transmission delay is reduced to 1.5 gate delays with the introduction of low latency transmission module and multi-rail encoding working manner makes the power consumption greatly reduced. Simulations on performance and power consumptions have been implemented under different fabrications and temperature variations. The results demonstrated that the proposed communication element can work up to 2.64 GHz with only 1. 252 mW dynamic power consumption on average. Therefore, it meets the requirements of high-speed low-power applications on chip networks.
