Abstract :
This is the first implementation of an FPGA based on autonomous fine-grain power-gating. To cut the power consumption of clock network and detect the activity of the cell efficiently, asynchronous architecture is full exploited. The proposed FPGA is fabricated in a 90 nm CMOS process with dual threshold voltages. It is more efficient in power than the synchronous FPGA at less than 30% utilization.
