    • The memory control system includes a memory unit, bus master(s), arbiter, and memory controller. The bus masters output bus use request signals, block mode signals, block information, and drive information for data and outputs data corresponding to block/receive read-out data. The arbiter receives request signals and drive information and outputs a master selection signal used to select a bus master to which access is permitted and the drive signal input from the selected bus master. The bus master selection unit receives block mode signals, block information and data corresponding to the bus masters and outputs the block mode signal, block information and bus master data selected according to the master selection signal. The memory controller receives drive information from the arbiter, block mode signal, and block information from the selection unit, and allows data corresponding to respective line block groups to be sequentially-stored in/read out from respective banks.
    • 存储器控制系统包括存储器单元,总线主机,仲裁器和存储器控制器。 总线主机输出总线使用请求信号,块模式信号,块信息和用于数据的驱动信息,并输出与块/接收读出数据相对应的数据。 仲裁器接收请求信号和驱动信息,并输出用于选择允许访问的总线主机的主选择信号和从所选总线主机输入的驱动信号。 总线主机选择单元接收块模式信号,块信息和对应于总线主机的数据,并输出根据主选择信号选择的块模式信号,块信息和总线主机数据。 存储器控制器从仲裁器,块模式信号和来自选择单元的块信息接收驱动信息,并且允许对应于各个行块组的数据被顺序地存储在/从各个存储体读出。

    • A specific image is saved in accordance with a video CODEC operated by the multi-frame structure. The method copies and saves a specific image in the process of compressing or decompressing the image of a videophone or a multimedia terminal. Each process utilizes first and second memory spaces of size commensurate with the size of images, and uses alternately two memory spaces as the area for a current image being coded or decoded and the area for a previous image. When the copy request of a specific image is issued during decompressing or compressing of the arbitrary (n)th frame, the image desired to be copied, corresponding to the previous image in the compressing or decompressing process of the (n+1)th frame, is treated as the image saved in said 1st memory space, thereupon the compressing or decompressing process of the (n+2)th frame is processed with respect to the 3rd memory space.
    • 根据由多帧结构操作的视频CODEC来保存特定图像。 该方法在压缩或解压缩视频电话或多媒体终端的图像的过程中复制并保存特定图像。 每个过程利用与图像大小相称的尺寸的第一和第二存储空间,并且交替使用两个存储空间作为当前图像被编码或解码的区域和先前图像的区域。 当在第(n + 1)帧的压缩或解压缩处理期间,在解压缩或压缩任意(n)帧期间发出特定图像的复制请求时,期望被复制的图像对应于先前图像, 被视为保存在所述第1个存储器空间中的图像,因此第(n + 2)个帧的压缩或解压缩处理相对于第3个存储器空间被处理。
