Optimizing Performance of Source Code for Real Time System
Main Article Content
Abstract
To optimize the performance of a program for real time system does not always mean what we might think. It is not just a matter of outright speed; sometimes it is about tuning the code and data so that it fits into a small memory footprint. It would be hard-pressed to find a programmer that does not want to make programs that run faster, regardless of the platform. Embedded programmers are not exception for that some take an almost fanatical approach to the job of optimizing their code for performance. As hardware becomes faster, cheaper, and more copious, some argue that performance optimization is less critical--particularly people that try to enforce deadlines on software development. Now a days most advanced hardware, combined with the latest in compiler optimization technology can not come even close to the performance benefits that can be attained by fixing some small probes at the beginning of programs or even going with an entirely different and much faster design.
