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