I did some testing of vorbis codec (Winamp plugin) on a Pentium 166 MMX, and found that the performance is pretty good. I got 3 % cpu utisization if I turned dithering off, and 5 % otherwise. This was with a 138 kbit song. It's pretty long to mp3 performance that was 0 to 1 % on that machine for a 128 kbit song. Also vorbis seems to have a larger working set, because if I play two songs at

...quot;. There are no other console messages (such as WINE FIXMEs) before this. After attaching a debugger (ollydbg) I found the following sequence seems to be the culprit (simplified to Cish code): (start @ 0x0041AF35) CPUID, RDTSC func CPUID, RDTSC func QueryPerformanceFrequency(&Frequency); QueryPerformanceCounter(&PerformanceCount1) CPUID, RDTSC func QueryPerformanceCounter(&PerformanceCount2) CPUID, RDTSC func do some math related to something blah = something * Frequency / (PerformanceCount2 - PerformanceCount1); The key issue being that PerformanceCount2 == PerformanceCount1 and so things blo...

Good afternoon! Thanks for the previous answers, now there was a question of efficiency. I use the formula of transformation YUV12->RGB: float r = nY + 1.371f * ( nV - 128 ); float g = nY - 0.698f * ( nV - 128 ) - 0.336f * ( nU - 128 ); float b = nY + 1.732f * ( nU - 128 ); frame[index + 0] = ClampFloatToByte( r ); frame[index + 1] = ClampFloatToByte(

I uninstalled wine, removed my home/.wine directory, untarred/unzipped the 20050419 source to a temporary directory and

Hi all, I'm currently implementing quasi random generation (torus) on R (package randtoolbox available on CRAN). Even if it is not a great idea, I decided to use the machine time to initiate the seed. So when the seed is not specified by the user, the pkg uses the time machine time. Hence the following R code should produce different uniform variates : > for(i in

...ime is accurate as expected, but it's sorry to get some notice it 's not accurate either. so it sets the RTC's rate from 15.625ms(64HZ) to 976.562us(1024HZ) again and again..., at last, results in a slow system timer in vm. there is also a frequently called function going into my eyes: QueryPerformanceCounter. what my problems are: 1 why the JVM sets the same RTC's rate 976562 down to the coms again and again? what he found is abnormal? 2 even a abnormal user program calls create_periodic_time to set the rate again and again, how do we avoid the influence upon our time in vm? how do we compensa...
