VciFrameBuffer

1) Functional Description

This VCI target can be used to display RVB or YUV images. It contains a buffer whose size is defined as the product [number_of_lines * number_of_pixel_per_line * number_of_bytes_per_pixel]. It does not contain any memory mapped registers, and supports both read & write accesses (including bursts).
