目前，很少有工具可以帮助FPGA开发人员将为通用处理器设计的算法转换为针对FPGA进行精度优化的算法。这项任务需要对算法和目标硬件都有广泛的了解。我们提出了一个设计时工具Precis，它可以帮助开发人员分析MATLAB中指定算法的精度要求。通过模拟、用户输入和程序分析的结合使用，我们展示了一种精度分析的方法，可以帮助开发人员集中精力进行手工精度优化。
Currently, few tools exist to aid the FPGA developer in translating an algorithm designed for a general-purpose-processor into one that is precision-optimized for FPGAs. This task requires extensive knowledge of both the algorithm and the target hardware. We present a design-time tool, Precis, which assists the developer in analyzing the precision requirements of algorithms specified in MATLAB. Through the combined use of simulation, user input, and program analysis, we demonstrate a methodology for precision analysis that can aid the developer in focusing their manual precision optimization efforts.
