23.7.2.1
Processing Modes
RLD supports only two processing modes – ‘in operation’ mode and ‘disabled’ mode.
23.8 Control Flow
23.8.1
Example Control Flow
1) microcontroller decodes TGA header info:
o
BitPerPixel
o
Source size
o
picture dimensions --> number of decompressed bytes
configuration of RLD:
2) reset OFIFO, IFIFO
3) set bpp-format
4) set target number of bytes
5) Configure AHB master IF
o
e.g. Dest. Address in Video Memory
6) Enable RLD
Deliver compressed data to RLD AHB slave.
Case A: compressed data source is AHB slave:
