基于GPU的二维离散小波变换快速计算
Fast 2D DWT Calculation Based on GPU
摘要
Abstract
By analyzing the DWT's polyphase representation and CPU's general-purpose computation model, this study presents a 2D DWT algorithm based on GPU and polyphase, which combines with modem GPU's multi-texture property and multiple render targets property. The computing form is well suited to GPU' s SIMD architecture in the method presented. The number of texture visit is significantly reduced. The GPU's vector processing ability and 2D address accessing ability is well utilized. The experimental result shows that the processing speed is greatly improved.关键词
