摘要
针对线阵CCD输出数据的处理需要,介绍了2048点FFT在TMS320C240x定点DSP上的实现。FFT算法程序采用汇编语言编写,可通过C语言函数调用,因此具有实现简单、高效的特点,且扩展性和兼容性强,可运行于嵌入式线阵CCD光谱探测系统中。
Because of the demand of data processing in linear CCD, this paper introduces the realization of 2048 points FFT in TMS320C240x fixed-ooint DSP. Arithmetic program of FFT is programmed in assembly code ,and it can be C function So it has the features of easy realization, high efficiency, good expansibility and compatibility.It had run in the embedded system for linear CCD spectral detection successfully.
