Abstract(in English) | This paper presents an asynchronous FPGA that combines the 4-phase dual-rail encoding and the Level-Encoded Dual-Rail (LEDR) encoding. The 4-phase dual-rail encoding is employed to achieve small area for function units, while the LEDR encoding is employed to achieve high throughput and low power for the data transfer using programmable interconnection resources. Area-efficient protocol converters are also proposed in transistor-level optimization. The proposed architecture is designed using a 90nm CMOS process. Compared to the 4-phase-dual-rail-based FPGA, the throughput and the power consumption are respectively by 45% higher and by 36% lower with almost the same transisitor count. Compared to the LEDR-based FPGA, the transistor count is by 35% lower with almost the same power consumption. |
