摘要

在嵌入式系统中，功耗和执行时间是影响性能的重要因素。代码质量决定了性能因素，而这些因素受编译器的影响很大。在本文中，我们从动态指令的数量和编译代码的大小两方面对GCC 4.7.1和GCC 4.2.2在EEMBC架构上的性能进行了比较。结果表明，GCC 4.7减少了6.8%的动态指令，但比GCC 4.2.2增加了2.9%的代码大小。

Performance evaluation of GCC 4.7.1 on EISC

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.
