Sometimes the fpga
blocks get big, too big for, say, a 4 mbit eprom, so our rom builder
program compresses them and the uP decompresses at runtime...

I expect that sooner or later Xilinx will add decompression hardware
to the FPGAs themselves to take advantage of that (significant!) gain
you're seeing... they already have some versions that decrypt the
bitstream, as I recall, adding decompression to that seems pretty
straightforward.


"What time is it?"

"Wait, my wrist watch seems to have problems with the bootloader"


As it says in "The inmates are running the asylum",
"When you cross a microwave with a computer, what do you get?"
"A computer."
"When you cross a toaster with a computer, what do you get?"
"That's right, a computer."

I like analogue things.

I've never owned a watch. I don't want some gadget strapped to my
wrist, telling me what to do when.
