RTLinux Boasts Single-Digit uSec Responsiveness

Posted by ScuttleMonkey on Monday September 12, 2005 @06:02PM from the speedy-gonzales-makes-his-linux-debut dept.

An anonymous reader writes "A Linux implementation delivering single-digit microsecond responsiveness on 64-bit dual-core AMD Opteron processors is being demonstrated at the Embedded Systems Conference in Boston this week. From the article: "According to FSMLabs, an AMD Opteron 265 dual-core system running RTLinux can deliver guaranteed interrupt latencies of no more than five microseconds, with scheduling jitter of no more than eight microseconds, even with Linux under a heavy load." Heck, with numbers like that it seems like Linux could run circles around XP Pro for audio/video apps such as streaming, recording, and playback!"

You say that like it's a hard mark to hit.

It has to go down to 3usec just to keep up with my double click speed.

You need raw CPU for that, not fast interrupts
That's unfortunate - I cooked mine a while back.
