| 摘 要： | 针对电池供电仪器中对FIR数字滤波的需求与低功耗、低成本设计约束的矛盾,提出了一种改进的、专为无硬件乘法器MSP430单片机使用的高时间效率FIR滤波算法,并根据该算法研制了相应的工具软件,能根据Matlab产生的FIR滤波器系数文件和用户指定的A/D转换精度等指标自动生成MSP430汇编语言源码.实际测试表明,该工具合成的FIR滤波代码完全达到人工编码的质量,耗时仅为等效C语言编码的8.7%,可用于所有无乘法器的MSP430单片机,有助于程序员大幅提高FIR滤波程序开发效率.

| Abstract: | In order to impliment FIR digital filter in battery-powered instruments with low-cost,low-power,an improved high efficiency FIR filter algorithm for non-multiplier MSP430 microcontroller is proposed,and a code synthesizer tool based on this algorithm is also developed,which imports Matlab-generated filter's coefficient file and synthesizes MSP430 source code according to user-specified A/D resolution.Experiment results show that the tool-generated codes achieve the same quality as manual coding and consumes... |
