pSOS to Real-Time Linux Conversion Our work on this project for the National Research Council involved the migration of an existing VMEbus control system from obsolete hardware and pSOS to modern hardware and real-time Linux configured for hard real-time. Our deliverables included:

+ Hardware selection (bus standard, processor board, analog I/O, digital I/O, chassis) + recommendations for the system software: development environment, real-time operating system and tools + redesign of the task-based, flat address space used by pSOS to Linux processes in user space and kernel space + device driver development for analogue and digital I/O hardware + development of a software upgrade strategy + coding, integration and final commissioning + documentation and support

The control system represents a system with hard real-time constraints. The investigation into the suitability of Linux for the project included measuring interrupt and context-switch latencies for various possible Linux kernels and sub-kernels. The options considered include using standard Linux distributions (2.4.27 and 2.6.8) as well as using RTAI and LXRT with the Linux 2.4 kernel. The technique used to measure latency and the results are documented in the whitepaper available on our website.
