Now many DSP systemsneed the fixed-point FFT to improve the speed of image processing .The precision in FFT calculation brought by the word length should be thought much of in the system designing . A precision analysis was put forward in this paper about the fixed-point FFT , and the max...

We propose a method in this paper in which the row-transform results of FFT are accessed in tiling...

图形处理器（ＧＰＵ）为ＳＩＭＤ架构，决定了它非常适合处理大量数据诸如图像、音频的这类任务。早期的ＧＰＵ由于是固定管线结构，自由度非常小，人们难以利用其进行３Ｄ图形运算之外的工作。自从Ｍｉｃｒｏｓｏｆｔ推出ＤｉｒｅｃｔＸ８以后，ＧＰＵ工作管线中加入了可编程单元，使得人们可以使用ＧＰＵ进行一些通用的...

There is also disagreement on the magnitude of the normalizing factor c. This is sometimes set to 1 for the forward transform, sometimes to M*N, and sometimes (in case of the unitary FFT) to. Especially in image processing applications the DC term is shifted to the center of the image....
