这是一本关于代码优化的书，虽然电脑技术发展迅速，但是要处理的现实问题也越来越复杂，不可能一味地发展硬件来迎合处理复杂问题的需要，实际上代码还有很大的优化空间，我们可以利用有限的硬件资源发挥出最大的功效。这本书需要一定的汇编基础。-This is a book about code optimization, although the rapid development of computer technology, but also to deal with more complex practical problems can not indulge in the development of hardware to meet the needs of dealing with complex issues, in fact, there is still much code optimization space, we can use the limited hardware resources to achieve the greatest effect. This book is a compilation of some basic needs.
