Abstract :
In an embedded system, power consumption and execution time are important factors in performance. Code quality determines the performance factors, which is greatly influenced by a compiler. In this paper, we evaluate the performance of GCC 4.7.1 in comparison of that of GCC 4.2.2 on the EISC architecture with EEMBC in terms of the number of dynamic instructions and compiled code size. The results show that GCC 4.7 reduces 6.8% of the dynamic instructions, but increases 2.9% of code size from GCC 4.2.2.
