威盛笔试题
早上记起有威盛的笔试，隐约记得好像是9点，
到了一看，发现不到30人，当时心里还说，怪不得选
这么小的教室，有道理，呵呵！后来才知道笔试时间是
9：30，而且后面来了很多人，四个人的桌子坐了5，6个人
还有很多兄弟站着答题，即使这样，还有很多人没地方，结果
没让他们考试。这也罢了，考到一半居然有人进来轰人，
真是faint。
既然考过了，给后人做点贡献吧。
考题一共七套，应聘不同的职位采用不同考题。其实这欧都不知道，
考场才知道，于是随便选了一个logic。一共十道题，
1.写你最近遇到的一个问题及解决方法，可以是工作上和生活上的任何事情
英文做答。easy，当作英文小短文写了。
2.有点忘了，好像是说除了ICs以外，还有一些什么东西的主要作用（忘了）
3.设计一个全加器
4.用CMOS技术画出用verilog表示的z=s?A:B的结构图。
5.也是跟verilog有关的，好像是给出时序，输入，设计什么东西之类的'，也记不太清！
6.给一个黑匣子，有输入X，时序CK，输出Y，给定settimeY和xxxtimeZ，问Y或者Z或者
Y+Z能否为negativetime,why?应该是这样的
7.给你一堆名词，举例他们的作用，
有PCI、ECC(?)、DDR、interrupt、pipeline
8.好像是设计一个自动售货机系统，卖soda水的，只能投进三种硬币，要正确的找回钱数
给出详细的设计步骤和方法，画出框图，什么输入输出什么的自己定
9.10被轰出了教室，没看！
个人感觉：考试及其混乱，可以看书，也经常有人相互交流。这么多人居然着这么小
一个教室，还考到一半被人轰了出来，真是让我对威盛的印象大打折扣。

We have words for banana and stick which help us to think about these things when they are not in ___27___.Even a small child knowing the words “banana” and “stick” has an idea of their relationship and is able to think “stick” together with “banana” and to remember this long enough to pick the stick ___28___ behind and use it on the banana.

For those watching, it is a top beauty nothing else can match. For skiers, it is a wonderful personal experience, and a thrilling test of mind, muscle and nerves. More and more Americans are discovering this thrill for themselves. Not long ago, skiing had no part in the American sport scene. If it were thought of at all, it was purely as a European sport. Then came the 1932 Winter Olympics at Lake Placid, New York. Americans got their first good look at skiing and made for the hills. Today ski trains make regular runs from our cities to the great, white outdoors. In addition to joy and cheer and excitement, skiing offers something more. It is a sport less expensive and for the young, the act of skiing is often mastered in a very short time. The special thrill of skiing is expressed by Buddy Werner.“It's all up to you,”he says.“No teammate can help. You're alone. It's against the snow, yourself. You're a brave fighter.” 31.Americans first understood and began skiing ______. A. about 50 years B. about 60 years ago C. not long ago D. in 1932 32.Besides giving us amusement and pleasure, skiing has some more virtues:______. A. a sport cheaper and easier to learn B. a sport fit for both men and women C. a sport outside, though expensive D. a sport both on snow and on water 33.According to Buddy Werner, the special thrill of skiing lies in the fact that ______. A. nobody can help B. you are skiing with teammates C. you're skiing on the mountains D. it can show you are brave 1：一个函数如下 char *f { char a[5]； char b[5]; a[0]='a'; a[1]='b'; a[2]='c'; a[3]='d'; a[4]='e'; strcpy(b,a); return b; } 请问：一：该函数中用a作为一个字符串是否存在问题？ 二、该函数返回的b是否可用，为什么？ 2：函数如下 void f() { char *a; a=(char*)malloc(5); strcpy(a,“abc”); a=“cde”; free(a); } 请问：该函数存在哪些问题？ 1. Select ONE of the following projects to discuss: a. Signal Filtering: You are given a sampled realtime waveform consisting of a sensor reading mixed with highly periodic impulses and high frequency noi se.The desired output is the realtime filtered sensor signal with the impulses and noise removed, and a readout of the impulse period. The FFT may not be us ed. b. Interrupt Processing.A headware register consisting of eight independen t edge triggered latches is used to record external asynchronous interrupt req uests.

How does that software assure that no interrupt request is ever missed? c.
