| 摘 要： | 提出了一种便捷的模糊推理系统在DSP(数字信号处理器)上的实现方法,详述了利用MATLAB的模糊逻辑工具箱对模糊系统建模、算法模拟及在TMS320VC5509系统上的实现过程,对实现中遇到的问题给出了相应的解决方法。结合程序特点和硬件结构对代码进行了优化。通过实例证明,按此方法在DSP上实现的模糊推理系统和在MATLAB中算法模拟的输出一致,优化后代码的运行时间减少了约四分之一。

| Abstract: | A nimble method to realize fuzzy inference system in DSP was advanced. Whole process of modeling fuzzy inference system with fuzzy logic toolbox of MATLAB, arithmetic simulation and realization in TMS320VC5509 system were dwelled on. Solutions to problems encountered in the process were given. Program code was optimized according to traits of the program and specific hardware structure. It was proved by examples that output of fuzzy inference system realized in DSP with this method coincide with output of arithmetic simulation in MATLAB and runtime of optimized program code was reduced about 25 percent. |
