    • An SRAM is used as a pixel buffer which stores a partial image region copied from a frame buffer. A vertical filter reads a pair of target pixels arranged in a vertical direction from the pixel buffer and performs a filtering process of a discrete wavelet transform in the vertical direction. An intermediate result obtained in the filtering process is stored in a register. The vertical filter uses the intermediate result in filtering the next two pixels. A horizontal filter receives two transformed results from the vertical filter and performs a filtering process on the transformed results in the horizontal direction. The intermediate results obtained in the horizontal filtering are also stored in a register and utilized in the next filtering.
    • SRAM用作存储从帧缓冲器复制的部分图像区域的像素缓冲器。 垂直滤波器从像素缓冲器读取沿垂直方向布置的一对目标像素,并且在垂直方向上执行离散小波变换的滤波处理。 在滤波处理中获得的中间结果存储在寄存器中。 垂直滤波器使用中间结果来过滤接下来的两个像素。 水平滤波器从垂直滤波器接收两个变换结果,并对水平方向上的变换结果执行滤波处理。 在水平滤波中获得的中间结果也存储在寄存器中,并用于下一次滤波。
