Abstract
A computer system includes a pair of display devices, such as cathode ray tubes (CRT's) or liquid crystal displays (LCD's) for providing a visible display to a user of the computer system. The computer system includes a video display controller (VDC) providing for simultaneous display of different images on the pair of display devices. The VDC includes a display data processing circuit (DDPC) which is variably configurable to provide decoding of data words from a first bit-word format as received from a display first-in-first-out (FIFO) memory to a second bit-word format as required by a particular one of the pair of display devices. The DDPC is variably configurable to allow the pair of display devices to each receive driving signals providing the simultaneous differing images, and which driving signals originate with the bit-words allocated to each particular one of the pair of display devices. Accordingly, the DDPC simultaneously decodes bit-words from the first bit-word format to a pair of second bit-word formats, which second bit-word formats need not be the same, but can differ depending on the type of display device receiving the corresponding driving signals.
