HUB75 LED Panel driver IP core

This core allows to drive LED panel chains using the 'classic' HUB75 protocol. The default top level contains a frame buffer but it's also possible to re-use the lower level components to drive a display without the need for a full frame buffer and just generate the pixel data 'just-in-time'.

The LEDS are modulated using Binary Coded Modulation which allow to efficiently vary their intensity efficiently. This video by Mike Harisson explains the concept of BCM very well.

The geometry of the panel and various aspecs are fully configurable through parameters given to the cores.

See the doc/ directory for more information about the internals of this core.
