今天去考了这个,如果过的话就可以选别的课,关键是现在USC EE CS学生很多容易选不到好课。之前准备这个考试的时候网上各种查不到别人的经验,所以我就来写一个让以后要考的人心里有个底。457 computer system organization有用是挺有用的但是我对554 [backcolor=rgb(255,255,255)]real-time computer system非常感兴趣 且想转CS所以想尽快这个学期就修掉554 可是需要457的prerequisite 所以想考考看。[/backcolor]

[backcolor=rgb(255,255,255)]这个考试不收钱,考的不好没有损失。[/backcolor]

[backcolor=rgb(255,255,255)]考纲USC EE网上有,但是与考题比起来感觉不是很全,不过基本是考纲涉及的几个面。考题是50道单选题1个小时完成 分成5 6大类 大类有点记不清了 大概有 各种数字电路原理;计算机结构; 内存和缓存(地址的block结构什么的); pipeline ;multiprocessor;大概就是这几个类别吧,题目难是不难都是基础知识,关键看你知道不知道,最好把考纲上推荐的那本教材通读一下,尤其是那些涉及以上几个类别的东西的原理记住,琐碎的东西不用记。[/backcolor]
