2008年5月12日下午2点36分，突然觉得电脑和桌子晃了一下，开始我还以为自己头晕眼
花了呢，听同事说了句：是不是地震呢？我才反应过来，一时间感觉自己像是在摇篮上。
那咱赶紧下楼吧！随着一声招呼，我一时恐慌起身就想跑，看有同事拿手机，拿包的。
我折身拎起起包、手机，随着大伙往外急走。地震了不能乘电梯，没办法只能跑楼梯了
，18楼啊！平时宁等5分钟电梯也不走楼梯的我，为了生命（看来我还是很惜命的，呵
呵！）毫不犹豫地顺着楼梯往下跑，由于跑的快，再加上心有恐慌之感，两条腿开始发
颤。觉得这18层怎么也到不了底！
我和一同事算是跑得快的，跑到楼下已有许多人聚集在了马路边上，喘口气赶紧给同城
、异城朋友、家乡父母打个电话，大部分都挺好，只有身在四川的同学联系不上，不知
道怎么样了。
大概有20分钟，觉得好像也没什么事了，回到单位，再看新闻，全国各地都有震感。四
川那边最为严重，但愿不要再有什么遭难了。
08年真是多事之秋啊！
过个年吧,雪灾了
传个火炬吧,藏独了
发展个农村医疗吧,手足口了
买点股票吧,大小非了
坐个火车吧,出轨了
在家呆著吧,地震了
今天大家都在谈论地震的原因，都说三峡截坝

惯例是用什么算法?
我脚着, 是不是从外往里连, 每连条线都让还没连起的点在新连线的同一侧....
但是不会证明
不知道这个问题怎么称呼? 有没有link?
谢~

三个数分别是2.04, 2.03, 1.96。表示现在负载很重吗？

我的本本有一套正版的vista home edition
我又自己攒了个兼容机，请问我能不能在兼容机安装vista ultimate 64-bit MSDN版的
操作系统，然后用本本上的那个激活码来激活？

I have done a couple of small fpga projects with verilog. I am
looking for some follow-up fun projects to increase my experience and
exposure to FPGA/verilog?
I am thinking of interfacing with the memory
blocks on the xilinx board and do some memory IO there. I've recently
done a music player through serial interface. I want to use the
onboard USB interface or ethernet interface, but I am not sure how to
proceed. The usb interface is currently used to program the board and
the ethernet i

这题好像是个简单的递归啊
没仔细看，我好像被问过

应该是不能激活。但是，你试试无妨。
原因是WindowsXP安装后会监视系统硬件的变化，如果硬件变化很大（多于6项），就会认为是
换成新电脑。vista安装后会有类似的系统变化监视。

技术这个东西，如果你不在行业里，有所了解就好了，没必要钻很深
等进了行业，再学不迟

not sure which xilinx board u are talking about, but shouldnt there be an
extra USB port besides the one used for programming the device?

no way. home edition 和 ultimate 的 key 不一样

I am using xilinx 3a, it has a single usb interface currently used by impact
to download program to the board.
yeah, i am doing it as a hobby, so it's ok that i am making slow progress.
please don't hesitate to point me to something intersting to do with my
board. It's a lot of money invested in the board. :)
thanks,

that usb interface on your board is for programming. I think it is not conn
ected to the FPGA at all. check out your manual for details.
So you can use it unless you do some white wire work. Xilinx has USB ip for
sale but it is not cheap comparing with your board.

what do you think about the IPs from opencores? Ideally I want to use the
ethernet interface. Has anyone used open core IPs?
I don't know how to use the IPs from open core on my spartan3A board. It'd
be fantastic if I could learn how to do that. They have tons of IPs.

a lot of opencores are working or close-to-working modules. you can give
them a shot and often times you might need to modify them a bit to be fully
functional, but they're definitely a good place to start your project
