In this paper we present a method for FPGA datapath precision optimization subject to user-defined area and error constraints. This work builds upon our previous research [Précis: A design-time precision analysis tool] which presented a methodology for optimizing for dynamic range-the most significant bit position. In this work, we present an automated optimization technique for the least-significant bit position of circuit datapaths. We present results describing the effectiveness of our methods on typical signal and image processing kernels.
