A mixed-mode FPAA SoC for analog-enhanced signal processing

Abstract

We present the RASP 2.9v, an FPAA for mixed-signal computation with an emphasis on enhanced digital support. This 25mm2, 350nm CMOS chip includes on-chip compilable DACs, dynamic reconfigurability and digital storage, and 76,000 programmable elements. We demonstrate an analog image-transform processor, an arbitrary waveform generator, and a mixed-mode FIR filter.
