Optimization... Is it right for you?

"So, the software isn't fast enough...what next?" While the temptation to "dive in" and have a go at optimization can sometimes be very strong, a bit of planning, preparation and understanding what you are aiming for can provide far better results.

Understanding the value of WCET optimisation within high-integrity real-time software

High-integrity software is typically thought of as being carefully constructed according to rigorous development procedures that primarily ensure its functional correctness. One casualty of this process can be run-time performance but, given the relatively small number of units being produced, the run-time performance can be addressed by over-specifying the hardware.

Welcome to the Rapita Systems blog

Welcome to the new Rapita Systems blog. This is the place where you can learn about and discuss software and real-time embedded systems verification and development issues. If you're aware of what we do at Rapita, you'll know we're more than a little obsessed with the real-time part of real-time embedded systems and worst-case execution time (WCET) analysis. In the course of our work we've come up with quite a few optimization tricks to help anyone else who shares our interest in these specialist fields.
