Display processor updating its color map memories from the serial output port of a video random-access memory

摘要: A display processor for a computer with graphics capability includes color map memories addressed by portions of pixel codes during line trace intervals. The read-outs from these provide the primary component signals which drive monitor kinescope are derived. codes, memory addresses derived, supplied at video rate to serial output port dual-ported random access memory. loaded new data retrace By supplying this random-access memory, can be rapidly updated.
