in some debugger then ther can be some time delays when you
pressing buttons. We can measure them with asm command
rdtsc
this instruction read time-stamp counter into edx:eax in our programm will be enought values from
eax
function for c that uses rdtsc is
extern int get_timer()
in fasm it looks like
get_timer: rdtsc ret
ther is writen code
s = get_timer();
for (i=0;i<10000;i++)
{
}
e = get_timer();
d = e - s;
average time to execute 10000 is 70069 ticks for value
on with we detecting how fast working code i have choose
twice of average 120000 if execution time is larger then
probably it is debuged.
Compile
make
