PALs for RS-170 Analog
These PALs (
RS-170.ex2
) implement analog video capture for 60 Hz / 525 line interlaced
cameras. These PALs are example 2 of the ALFAST distribution.
The timing parameters are programmed into the PALs and require re-compilation to
change. Because of the split “crosspoint switch” in the FastImage 1300, the mapping of
input taps to processors is as follows:
Tap 1 (RS-170)
-
TriMedia 0
Tap 2 (RS-170)
-
TriMedia 2
Tap 3 (RS-170)
-
TriMedia 1
Tap 4 (NTSC / PAL)
-
TriMedia 3

PALs for NTSC Analog
These PALs (
NTSC.ex3
) implement analog video capture for NTSC/PAL cameras. These
PALs are example 3 of the ALFast distribution.
The “crosspoint switch” PALs (PAL3 and PAL4) connect the output of the EVIP to all four
TriMedia.

DIGITAL CAMERAS
A. Digital Input
Digital video input lines allow direct connection of digital line-scan or area-scan cameras of up
to 32 bits. The 32 Digital data inputs are received by high-speed LVDS differential receivers.
