- Abstract
- An asynchronous circuit design methodology has been introduced as a novelty approach to future digital system design. Nevertheless, in order to implement the asynchronous circuit, there are various limitations. Especially, for the implementation on a commercialized field programmable gate array (FPGA), the vendors and design tools mainly support only synchronous circuit design. In this paper, we propose design techniques for implementing the asynchronous circuit on the commercial FPGA using the provided design tool. Then, with the proposed design techniques, we designed an asynchronous micro-controller based on a TI MSP430 instruction set architecture (ISA). We observe that the asynchronous core consumes lower power than the synchronous one. In addition, the asynchronous core also shows much more durability under conditions of unstable power supplies compared to the synchronous counterpart.
