Re: [f-cpu] about Gaetan's work




Yann Guidon a écrit :

Hello !

Gaetan will submit his report on friday, in a public session i believe.

Some of his working documents are at http://xeberon.net/temp/
and it's in french (translation will be done next)

and i'm proofreading some of it.
currently i'm looking at fcpu-fpu-adder-appendix.pdf

One remark :
generic (
  WIDTH : natural := 64
);

and an assertion that checks WIDTH mod 64 ....

F-CPU's data widths are powers of two, not all multiples of 64.
in fact i checked before with power of 2, but i saw Micheel doing this, i thought i
should also do this

--pragma synthesis_off
begin
assert (WIDTH >= 64) and (WIDTH mod 64 = 0)
report "width of IAdd must be an integer multiple of 64"
severity failure;
--pragma synthesis_on

Gaetan doesn't seem to use a cloning wrapper for handling
larger widths transparently. Did i miss a discussion ?
(highly probable)
it's more probable that Gaetan didn't make it in a good way...

reading the rest,
YG
