%T Predictable response times and portable hard real\-time systems with TRANS\-RTXc on the Transputer %A Eric Verhulst, Hans Thielemans %E Hussein S. M. Zedan %B OUG\-13: Real\-Time Systems with Transputers %X The transputer is a flexible processor, very well suited for applications where modularity and distributed operation are prime requirements, like in process control. Nevertheless, its basic FIFO\-scheduling algorithm, makes its application for real\-time processing quite difficult. This problem has now been solved by the development of a preemptive scheduling algorithm. This algorithm was used to port an existing real\-time kernel to the Transputer. In addition, by taking account of the specific nature of the Transputer, much better performance and flexibility have been obtained.
