Message-ID: <2635@s3.ireq.hydro.qc.ca> Date: 28 Aug 90 05:25:34 GMT References: Sender: root@s3.ireq.hydro.qc.ca Reply-To: bilbo@ireq.hydro.qc.ca Organization: IREQ, Hydro-Quebec Lines: 25 We provide an Object-Oriented Real Time Executive for 80x86 machines. The executive is written in C++ and is to be com- piled with Zortech C++ compiler (2.x). A ROM locator is also available to get Intel Hex or hp absolute code for your PROM programmer. On a 20 MHz DELL 210 computer we can get more than 60000 context switch per second between PROCESS. On an 9 MHz 286 AT compatible we get 22000 context switch per second. But context switch time depend on what is saved/restored during the switch (CPU reg, FPM, MMU, ...) and is do not reveal the performance of the system. Scheduling methods is at least as much important.
