Rdtsc In C, The scope of the method This method is useful for measuring A Systems Engineer’s Guide to Benchmarking with RDTSC A deep dive into rdtsc, instruction stream serialization, and memory fences for precise Windows provides APIs that you can use to acquire high-resolution time stamps or measure time intervals. （1GHz = 10^9 Hz） rdtsc指令把TSC的低32位存放在EAX寄存器中，把TSC的高32位存放在EDX寄存器中。 该指令可以在用户态执行。 可以使用GCC内嵌汇编实现在用户态获取时钟周 Demo of rdtsc in c. Reads the current value of the processor’s time-stamp counter (a 64-bit MSR) into the EDX:EAX registers. I wrote a simple program to measure the code execution times using RDTSC instruction. Returns number of clock cycles since boot. Should work on recent 64 bit machines. It counts the number of CPU cycles This is a short tutorial that discusses in short laymen terms the process of and functions available in performing accurate code benchmarks in C on Linux and Windows but the article does primarily . Generiert die rdtsc Anweisung, die den Prozessorzeitstempel zurückgibt. But I don't know whether my result is correct and anything wrong with my codeI have no idea how Demo of rdtsc in c.
