Abstract
This paper presents one-color two-phase asynchronous communication links for a high-performance asynchronous system. The proposed communication links based on simple one-color encoding is effectively connected to processing cores. Since the communication is controlled by simultaneous handshaking, where a request and an acknowledge signals are overlapped, the number of communication steps is greatly reduced. Moreover, the use of multiple-valued current-mode circuit makes it possible to realize asynchronous communication with just two wires. The asynchronous transmission circuits based on the proposed encoding are implemented and evaluated using HSPICE simulation with 0.13 um CMOS technology. Throughput of the proposed 2-bit transmission attains 0.45Gbps/wire, which is three times faster than that of the conventional two-color two-phase transmission.
本文提出了一种高性能异步系统的单色两相异步通信链路。所提出的基于简单单色编码的通信链路有效地连接到处理核心。由于通信是由同时握手控制的,其中请求和确认信号重叠,因此大大减少了通信步骤的数量。此外,多值电流模式电路的使用使得仅用两根电线就可以实现异步通信。采用0.13 um CMOS技术实现了基于该编码的异步传输电路,并进行了HSPICE仿真。提出的2位传输吞吐量达到0.45Gbps/线,比传统的双色两相传输速度快3倍。
