An Automatic Compiler Optimizations Selection Framework for Embedded Applications

Free registration required

Executive Summary

Optimizing compilers provide users with compiler options to maximize program performance. The selection of compiler options is important as the resulted performance can vary significantly. The best combination of compiler options is not only dependent on the program itself, but it also is highly related to the configuration of the system and the architecture of the processor that the program runs on. The determination of the best combination of compiler options is very complicated, as its complexity grows exponentially with the number of the optimization options the compiler offers. Many previous work attempts to shorten the search time by reducing the complexity of the problem.
