as-gps
- as-gps 包含基本的对访问廉价的Aisin-Seiki GPS 模块的支持,这一功能以前在mavin.com上是可用的。这个包也包括了几个简单的控制台工具来转储卫星状态,位置,和时间,并可同步化系统时钟。-as-a GPS contains the basic right to visit cheap Aisin - Seiki GPS module support this feature before in mavin.com is available. The package also
曼彻斯特码
- 今天看了一下从fpga上下的曼彻斯特编解码的程序,感觉不是很清楚,仿真了一下,更迷茫了,大家看看为啥这程序要这么编呢? 程序比较长,不过写的应该还是不错的,看了后应该有收获。 总的思路是这样: 1 通过一个高频的时钟检测wrn信号,如果检测到上升沿,则表明开始编码,将输入的8位数据转为串行,并编码,然后输出。 2 定时信号是从高频时钟16分频后得到的,在wrn上升沿后16分频使能,在编码结束后禁止分频输出。 3 no_bits_sent记录串行输出的位数,应该是从0010到1

网络校准时间
- 网络授时服务是在网络上设置一些时间服务器,用户通过Internet访问这些时间服务器就可同步本地计算机时钟的服务。-network time service on the network is set up some time server, Internet users visit those time servers can be synchronized to the local computer clock service.
generic_fifos
- Generic, multi-purpose FIFOs. Available as single clock and dual clock version, binary, lfsr, and gray encoded (dual clock only). All are parameterizable and use generic_memories for memory. These FIFOs are fully portable from FPGAs to ASICS.
FPGA-global-clk-design-
- FPGA的全局时钟应该是从晶振分出来的,最原始的频率。其他需要的各种频率都是在这个基础上利用PLL或者其他分频手段得到的;因为全局时钟需要驱动很多模块,所以全局时钟引脚需要有很大的驱动能力,FPGA一般都有一些专门的引脚用于作为全局时钟用,他们的驱动能力比较强-FPGA' s global clock should be divided out from the crystal, the frequency of the most original. Other needs of the
