i read that a 287 divides the speed of the clock. is the number of
cycles given in the book from intel about the number of cycles it takes
to do, say a multiplication, corespond to the original clock
speed or the speed after being divided by three?
i want to know also how much a 287 will speed up my machine when it does
pure arithmatic, mostly multiplication, addition and an ocasional
sqrt. it spends probably at least 98% of its time doing arithmatic.
gwoho liu.
