ROSETTA Configurable Dot Matrix Display Controller :: Overview
Other project properties
The ROSETTA Configurable Dot Matrix Display Controller core provides a modular expandable interface for any dimension displays build from LEDs dot matrix structures. This core can be configured for synthesis and P&R with any number of DM LEDs slices. These slices can be arranged in any number to form linear or plane screens.
In designs with a big number of slices, the number of pins required for the implementation device selected could collapse. In order to overcome this inconvenience, the output bus has a multiplexed structure, and the size of the display can be expanded using external buffer devices.
In limited size implementations, the display columns could optionally be serviced using the controller chip drivers, if a device with enough driving capability is used. On the other hand, the row lines will always need some external buffering.
