Real-Time Systems Scheduling

Three cross compilers hosted on a VAX/VMS for the Motorola 68020 processor have been evaluated. The target machine, a VME system with a MVME133 processor card and a MVME340 digital IO-card, has been set up in an environment with a function generator and an oscilloscope in order to measure the real time response. The compilers supply the run time kernel. It is possible to use Ada for real time applications, with the use of optimization of accept statements task switch times can come down to the order of 15 - 20 us.
