Single chip video system with separate clocks for memory controller, CRT controller |
摘要 |
A video system has a controller for controlling the transfer of data from a processor to a CRT monitor. The controller has two clocks and a CRT interface for synchronously interfacing the controller to the CRT monitor, a second interface for synchronously interfacing the controller to the processor. A first clock source provides timing for the CRT interface and is in synch with the timing of the CRT monitor. A second clock source provides timing for the processor interphase which is in synch with the timing of the processor.
