CPUIDLIB
Post by Michael Hutton on Sep 27th, 2009, 5:07pm

For those into their ASM programming they might find this library a useful add on to test for certain CPU features such as an FPU, MMX, SSE1-4 and more. You can find more detailed info about the CPUID instruction in your local friendly Intel documentation.

Instructions on how to use it are in the program.

Thanks. You might like to note that this line in your library:

Code:
IF USR(C%) THEN =TRUE ELSE =FALSE

can be directly replaced with this:

Code:
= USR(C%)<>0

which is (arguably) neater and avoids the 'end of function' (=) being buried inside another statement.

Good point. I'll revise it.
