Large-Scale FPAA Devices for Signal Processing Applications

We present a viewpoint showing that analog signal processing approaches are becoming configurable and programmable like their digital counterparts, while retaining a huge computational efficiency, for a given power budget, compared to their digital counterparts. We present recent results in programmable and configurable analog signal processing describing the widespread potential of these approaches. We also discuss issues with configurable systems, including size, power, and computational tradeoffs, as well as address the computational efficiency of these approaches.
