Jeri Ellsworth takes a look at the Papilio One and recommends it for FPGA beginners.

Soap spam next? ;)

I must say one has to really be a detective to figure out the technical data which is essential. And the FPGA doesn't look 680x0+AGA capable.

What about the Papilio Pro?

" The Papilio Pro (Spartan 6) has direct TMDS I/O support which means that DVI and HDMI interfaces can be implemented without any extra chips. "


It's the speed and electrical signal standard that determines if HDMI is possible. RocketPort should be sufficient.

Xilinx Spartan 6 - probably has enough capacity.

Again hard data lacks..
(specific chip and package, specific Mbit/s rate, specific electrical standard etc)

DVI is completely free to implement (asfaik). With HDMI there's even a fee on having the chip mounted or the specific connector.

NET CLK            LOC="P94"  | IOSTANDARD=LVTTL | PERIOD=31.25ns;               # CLK


32 Mbit/s = insufficient by magnitudes.

Just to make a simple comparision: 640*480 12-bpp 25-fps = 92 Mbit/s

Methinks the detective in you didn't try very hard...


The webpage in question is messy.
