Efika 5200B Project
Real-time linux OS comparisonin category Operating Systems

Project Summary
The real time capabilities of embedded systems are important for a range of applications where timing of tasks is critical, such as control systems like industrial automation, robotics platforms, carrier-grade telecommunication, just to name a few; many of the projects in the EFIKA developer programs also require critical timing provided by real-time operating systems. Generally, I plan to compare a range of opensource real-time Linux implementations on the EFIKA.
To start with I will compare Linux kernel 2.4 (as a base-line), Linux kernel 2.6, RTLinuxFree 3.1, RTAI (Real Time Application Interface), and LXRT.
This includes:
- Develop a set of benchmarks in a test control system, such benchmarks include measurements of different timing latencies.
- document the current PPC architecture status of each real-time linux OS.
- Contribute to certain PPC ports of real-time linux projects.
The test control system will be rather prosaic to start with using a programmable timer to measure latency and other benchmarking linux tools to increase the load on the target system (lmbench, netperf, threads, hackbench, dbench etc).
As a side project, myself and a small team of friends that are into hobby robotics will try out the EFIKA using best-of-breed real-time linux in a robotics platform for hardware robocup soccer.
