摘要

本文介绍一种新的DCT计算方法

它以现有的DCT快速算法为基础

利用超长指令的并行特征来提高DCT计算的性能.仿真结果表明:该方法的运算速度比普通的DCT计算方法提高73%

即便同快速算法相比

也可以提高24%的运算速度.

Abstract

In this paper

a new DCT computation algorithm is presented

which is based on existing fast DCT algorithm and has fully utilized the parallelism of very long instruction word (VLIW) architecture to achieve high speed performance.Simulation results show that this method can reduce more than 73% and 24% computing cycles

compared with normal and fast DCT computation algorithm respectively.
