This is my home working place where I can port software from little-endian machine to big-endian:Red table bought in IKEA. Right-bottom: Systemax server with Intel Core 2 Duo 2.6 ГГц (Slackware 12.2). Right-top: PowerMac G4 Cube (colored to black) with Debian 5.0 and preloaded libfreevec. Left-bottom: subwoofer Logitech, power adapter for Cube and Gigabit switch. Left-top: UPS CyberPower 1500AVR. In the center under the table: KVM IOGEAR (switching USB keyboard+mouse and VGA between both machines). In the center on the … Continue Reading

Again I tested new hardware using my memcpy benchmark – now for my 1st desktop on Intel Core 2 Duo 2.6 GHz and my 2nd desktop on PowerPC G4 450 MHz (black G4 Cube). Here you can see not-aligned (nal) and aligned (al) results and also “vectorized” results (G4-450v-nal and G4-450v-al) where memcpy was AltiVec optimized version from libfreevec v1.0.4.P.S. If you want optimized AltiVec versions of such functions as bmove512, memccpy, memchr, memcmp, … Continue Reading

Some benchmarks of memcpy function on my Compaq Presario S6000NX Celeron 2.7 GHz (Linux), PowerMac G4 400 MHz (Linux) and PowerBook G4 1.67 GHz (Linux and Mac OS X):As we can see vectorized memcpy on PowerPC G4 1.67 GHz almost twice as fast as Celeron 2.7 GHz (which is sometimes similar to speed of vectorized memcpy on PowerPC G4 400 MHz). Also we see that Mac OS X has vectorized memcpy by default. See source code of … Continue Reading
