I am trying to find out a quick way to clear memory. I used memset or
bzero function, but they are way too slow. I am trying to use assembly
language, but Gas doesn't recognize 'les' and 'reps ', can anybody help
me?
(use memset to clear a virtual screen memory is only twice faster than
transfering data from virtual screen to video ram using movedatal function.
As I know, data transfering to video ram is about 5-6 times slower than the
to regular memories. So there must be a quicker way!)
by the way, is there any good resources on AT&T assembler on the net?
