摘要
基于MOUSETRAP异步流水线结构提出了一种全局异步局部同步方式下的片上系统的异步互连接口架构.为实现异步接口电路的低功耗,对其进行了晶体管级的功耗优化设计.同时,利用基于多级供电电压控制下的延时可调机制,以缓解该异步互连中匹配延时链设计困难带来工艺可移植性差的问题.该接口适用于对数据传输率和功耗有较高要求的多电压供电片上系统设计.
A low-power system-on-chip (SOC) asynchronous interface in global asynchronous local synchronous (GALS) style, which based on MOUSETRAP asynchronous pipelines architecture, is presented. A transistor-level method is introduced to optimize the circuits' power-performance. A tunable delay mechanism based on multi-delay's power supply is used to improve the process portability of the asynchronous interface circuits. This asynchronous interface architecture can be applied to the multi-supply SOC design of which the high-speed data rate and low-power are mandatory.
