Architecture of an Asynchronous FPGA for Handshake-Component-Based Design

This paper presents a novel architecture of an asynchronous FPGA for handshake-component-based design. The handshakecomponent-based design is suitable for large-scale, complex asynchronous circuit because of its understandability. This paper proposes an areaefficient architecture of an FPGA that is suitable for handshake-componentbased asynchronous circuit. Moreover, the Four-Phase Dual-Rail encoding is employed to construct circuits robust to delay variation because the data paths are programmable in FPGA. The FPGA based on the proposed architecture is implemented in a 65 nm process. Its evaluation results show that the proposed FPGA can implement handshake components efficiently. key words: FPGA, reconfigurable LSI, self-timed circuit, asynchronous circuit
