ABSTRACT:
Video display apparatus is described in which video data is held in a dynamic random-access memory (DRAM). In each cycle, one processor access and four video accesses are made to be DRAM. The video data is de-skewed, by feeding it through two registers in series, so as to ensure that the four video data words can be sampled at equally spaced intervals, equal to one-fourth of the cycle.
