Aug 31, 2010 · The unit for frequency is Hz which is the same as 1/s or s^-1. To convert from frequency to length (really time) you have to compute the reciprocal value: length = 1/frequency. What is length (in ns) of one cycle on a 50 MegaHertz (MHz) computer? 1/(50*10^6 Hz) = 2*10^-8 s = 20*10^-9 s = 20 ns

Jul 28, 2013 · The simulator has a "time resolution" setting, which often defaults to nanoseconds... In which case, 5 ns / 2 comes out to be 2 ns so you end up with a period of 4ns! Set the simulator to picoseconds and all will be well (until you need fractions of a picosecond to represent your clock time anyway!)

Jul 13, 2021 · In the VHDL test bench, declared ''' t1 : time; t2 : time; ''' The simulation is in picoseconds. The assignment in architecure is ''' t1: now -- assign time to t1 t2: now -- assign time to t2 later point in test bench. ''' Question : How to convert the delta time in ps (t2-t1) to frequency? Either Hz or MHz or KHz, does not matter.

Sep 19, 2012 · The value of HZ varies across kernel versions and hardware platforms. On i386 the situation is as follows: on kernels up to and including 2.4.x, HZ was 100 giving a jiffy value of 0.01 seconds; starting with 2.6.0, HZ was raised to 1000, giving a jiffy of 0.001 seconds.

May 22, 2018 · For 10000 Hz I get ~9300 Hz Here is the code that I use to delay the while loop: import time count=0 while True: sample_rate=5000 time_start=time.perf_counter() count+=1 while (time.perf_counter()-time_start) < (1/sample_rate): pass if count == sample_rate: print(1/(time.perf_counter()-time_start)) count=0

Jun 24, 2014 · Assert position at the beginning of the string «^» Match a single character in the range between “a” and “z” «[a-z]{1}» Exactly 1 times «{1}» Match a single character present in the list below «[a-z0-9_]{3,13}» Between 3 and 13 times, as many times as possible, giving back as needed (greedy) «{3,13}» A character in the range between “a” and “z” «a-z» A character in ...

On my x86-64 Linux Ubuntu 18.04 system with the gcc compiler, clock_getres() returns a resolution of 1 ns. For both clock_gettime() and timespec_get() , I have also done empirical testing where I take 1000 timestamps rapidly, as fast as possible (see the get_estimated_resolution() function of my timinglib.c timing library), and look to see what ...

Jul 30, 2014 · ffmpeg -i video.avi -ar 22050 -ab 32 -f flv -s 320x240 video.flv -ar (Audio sampling rate in Hz) -ab (Audio bit rate in kbit/s) regarding the -ar and the -ab how do I know what rate to use? I got this ffmpeg command from a site somewhere and I was wondering how the person knew what values to put for the rates?

Apr 27, 2017 · @xdhmoore: That's correct, a cycle is a length of time, not a rate. The frequency is the rate. e.g. a 1 GHz CPU has a cycle time of 1 ns. OTOH, very often we use "cycles" as the base unit of measurement, like "addsd latency is 4 cycles". Because it's always 4 cycles on a given microarchitecture like Sylake, whether it's running at 800 MHz idle ...
