Ultra low power and high speed FPGA design with CNFET

초록

Both the capacity and the complexity of modern FPGA devices increase rapidly. Also, it is common that battery-powered embedded systems are equipped with FPGA devices. Therefore, reducing the power consumption of FPGA devices has become a very crucial issue. Not only dynamic power consumption but also leakage power consumption increases as the feature size to manufacture FPGA devices shrinks. To reduce the power consumption of FPGA devices, carbon-nanotube field effect transistor (CNFET) has emerged as a promising candidate for replacing silicon metal oxide semiconductor field effect transistor (Si-MOSFET). In this paper, we propose an FPGA slice design based on CNFET technology, and compare the performance and the power consumption characteristics of the proposed design with the same design based on Si-MOSFET. From the performance evaluation, we learned that the proposed design showed up to 5000 times better power-delay product (PDP) than the Si-MOSFET design. Especially reduction in power consumption was truly significant.
