We have developed 'SORIX 386/486' an AT&T SVR4.0 based real time UNIX system.

On a 80386 CPU running at 33 MHz we guarantee an interrupt latency time
of at most 135 us and a context switch latency of at most 325 us.

That means if an interrupt arrives it takes at most 135 us until
the execution of the interrupt handler starts.

For further information contact 'sorix386@norisc.erls01.siemens.de'.
