Architecture with centralized single memory for the transfer of video images

摘要

The invention relates to an architecture making it possible to store and transfer still or moving video images, the said architecture comprising at least one input circuit (E1, E2, . . . , En) allowing access for data intended to make up video images, a memory area (M) making it possible to store video images, at least one video image output circuit (S1, S2, . . . , Sj) and a video bus (B) intended to provide for the transfer of information between the memory area (M), the input circuit and the output circuit, characterized in that the memory area (M) is a general-purpose memory and in that the video bus (B) has a width L greater than or equal to the width of the memory area (M).P P The general-purpose memory is operated in a centralized manner by a control circuit (CTRL).PPThe invention applies to computer platforms dedicated to the transfer of Broadcast quality images or alternatively to video devices for built-up image animation. The architecture according to the invention can also comprise video image processing circuits (T1, T2, . . . , Tn)
