摘要

复杂信号处理算法在浮点精度中被指定。当它们的硬件实现需要定点精度时，就需要进行类型细化。本文给出了量化过程的方法和设计环境。该方法采用独立策略确定定点信号的MSB和LSB权重。它通过结合分析和基于仿真的方法的优势来缩短设计周期。

A methodology and design environment for DSP ASIC fixed point refinement

Complex signal processing algorithms are specified in floating point precision. When their hardware implementation requires fixed point precision, type refinement is needed. The paper presents a methodology and design environment for this quantization process. The method uses independent strategies for fixing MSB and LSB weights of fixed point signals. It enables short design cycles by combining the strengths of both analytical and simulation based methods.
