I may be wrong, but isn't the Time Stamp Counter (TSC) the on-chip counter that the Performance Counter uses?

Read an article at the Programmer's Workshop titled, "selecting timer functions" that makes reference to, but does not discuss, a timer function they refer to as Time Stamp Counter (TSC). Does anyone have any info on this function and/or can point to a resource that does.

Thanks

-P.S. I know about other timer functions, such as Performance Counter, GetTickCount, etc., so I'm really only interested in info on the TSC.

Yeah, read by the RDTSC instruction.
If available, QueryPerformanceCounter() maps to this instruction
