PutTxtCP 06h
Device
PE
Function
Store compressed pixel data with fixed
foreground or background colour into
Video RAM (finite command).
Source:
ULB input fifo with n*[coded colour ena-
ble data], n depends on compression factor
Target:
Rectangular area of pixels between start
and end point in selected layer in Video
RAM. Background pixels are written only
if BGCOL_EN = ’1’.
Registers
XYMAX
XYMIN
FGCOL
BGCOL_EN
BGCOL_COL
PPCMD_LAY
PPCMD_EN
PPCMD_DIR
PPCMD_MIR
IFIFO
PutPixel
07h MAU
Note:
Only the relevant bits of BGCOL and
FGCOL register are used (depends on the
colour depth).
Transfer single pixel data into Video RAM
(infinite command).
Source:
IFIFO with address/data pairs.
n*([L,X,Y], [single colour data]),
n = number of pixels
PPCMD_EN
IFIFO
Target:
Addressed pixel in Video RAM.
PutPxWd 08h MAU
Note:
IFIFO: LSB aligned pixel data, however
physical data in Video RAM is MSB
aligned
Transfer packetized pixel in data words
(pixel bursts) into Video RAM (infinite
command).
PPCMD_EN
IFIFO
Source:
IFIFO with n*([L,X,Y],[data word])
n = number of packet words
Target:
Successive pixels in Video RAM on
addressed position.
Note:
The number of pixels in the 32-bit word
depends on colour depth/layer. In Opposi-
tion to PutPixel command IFIFO data is
directly in Video RAM format. Especially
for 24 bit colour depht IFIFO data is MSB
aligned in this case.
