Video Controller
19.1 FEATURES
The following list summarizes the features of the video controller:
19.2 OPERATION
The video controller consists of a register set, DMA controller with FIFOs, and a video
control RAM array, as shown in Figure 19-2. The video controller RAM array provides the
proper sequencing and control signal generation needed to synchronize the datastream
through the FIFOs. The video controller, a standalone module, is programmed using a set
of configuration registers. Once the registers have been configured and the video controller
is enabled, the DMA controller initiates burst read cycles to display memory.
