Memory optimization

The term memory profiling refers to a wide range of application testing tasks related to computer memory, such as identifying memory corruption, memory leaks and optimizing memory usage. The QNX Momentics IDE, which is part of QNX SDP 6.5.0, includes tools to assist you with all of these tasks. However, this article focuses on the optimization of memory usage for better performance and smaller memory footprint. Memory efficiency is particularly critical for embedded software, where memory resources are very limited, especially with absence of swapping, and the need for processes that run continuously.
