Systems software technology and business
It is now possible to put together sophisticated and powerful embedded and control systems that are mostly composed of pre-existing working software. One of the demonstrations we showed at AMD’s recent embedded workshop was a small two processor (4 core) box running RTLinux and Windows XP. Embedded development teams for RTCore based products can mirror [...]
One way of defining modules is by what engineers have to know. If a program X consists of components X1 … Xn then we can say Xi is a module if a programmer can modify it without learning “much” about any other module. A second, related measure can be in terms of information hiding [...]
We added the “reservation” capability to RTCore real-time POSIX threads a couple of years ago. Normally, the client platform operating system shares the processor with RTCore threads as a completely pre-emptible low priority thread. This works exceptionally well. Worst case interrupt latencies of under 10 microseconds on Opterons and under 20 on Arm9s are possible [...]
