Abstract
A display control device for outputting display data to frame buffers includes an input for receiving portions of the display data, different portions being in raw form and in compressed form. A data controller determines, for each received portion, whether it is in compressed form or raw form and controls the received portion to move along a first, bypass, path if it is determined that the received portion of display data is in raw form and to control the received portion of display data to move along a second path to a decompression engine if it is determined that the received portion of display data is in compressed form. The decompression engine decompresses the particular portion of compressed display data and forwards a corresponding portion of decompressed display data along a third path, the portions of data from the first and third paths then being output to the frame buffers.
