Microsecond Delays on Non-Real Time Operating Systems

Abstract

We have developed microsecond timing and profiling software that runs on standard Windows [1] and Linux based operating systems. This software is orders of magnitudes better than most of the standard native functions in wide use.Our software libraries calibrate RDTSC in microseconds or seconds to provide two different types of delays: a "Guaranteed Minimum" and a precision "Long Delay", which releases to the kernel. Both return profiling information of the actual delay.
