A single memory architecture centralized for the transfer of video images

摘要

An architecture for storing and transferring still or animated video images is disclosed. Said architecture includes at least one input circuit (E1, E2, ..., En) for video image data access, a memory area (M) for storing video images, at least one video image output circuit (S1, S2, ..., Sj) and a video bus (B) for transferring data between the memory area (M), the input circuit and the output circuit. Said memory area (M) is a working area and the width (L) of the video bus (B) is no smaller than that of the memory area (M). The working area is under the centralised control of a control circuit (CTRL). Said architecture may be used in dedicated computer platforms for transferring broadcast-quality images, or in video devices for computer-generated image animation. Said architecture may further include video image processing circuits (T1, T2, ..., Tn).
