Due to high-speed switching and low power consumption, CNFET is expected to allow processor architects to adopt new microarchitecture in processor design; however, the nature of microprocessors implemented with CNFET (a.k.a., CNFET processors) is little known. In particular, performance, power consumption, and area of individual units within microprocessors placed-and-routed with CNFET have not been reported yet. In this paper, we show performance, power consumption, and area of two microprocessors (i.e., RSD and OpenSPARC T2) placed-and-routed with CNFET5 and CNFET7 technologies while comparing the experimental results with ASAP7, FreePDK15, and FreePDK45. Our experimental results show that processor units with CNFET7 consume up to 94.5% and 94.6% smaller power than those with ASAP7 at a frequency of 0.8 GHz in RSD and OpenSPARC T2 , respectively, in exchange for 2x area overheads, and CNFET5 that has the same area overhead as CNFET7 shows further reduction in power consumption when compared to CNFET7.CNFET (Carbon Nanotube Field Effect Transistor), which uses carbon nanotubes as transistor channels, is the next-generation MOSFET device and has a great potential in both improving the performance and reducing the power consumption of microprocessors.
