A 90-nm Low-Power FPGA for Battery-Powered Applications

Abstract

Programmable logic devices such as FPGAs are useful for a wide range of applications. However, FPGAs are not commonly used in battery-powered applications because they consume more power than ASICs and lack power management features. In this paper, we describe the design and implementation of <i>Pika</i>, a low-power FPGA core targeting battery-powered applications such as those in consumer and automotive markets. Our design uses the Xilinx Spartan-3 low-cost FPGA as a baseline and achieves substantial power savings through a series of power optimizations. The resulting architecture is compatible with existing commercial design tools. The implementation is done in a 90nm triple-oxide CMOS process. Compared to the baseline design, Pika consumes 46% less active power and 99% less standby power. Furthermore, it retains circuit and configuration state during standby mode, and wakes up from standby mode in approximately 100ns.
