Verilog HDL编写的键盘扫描程序，考虑了判断按键弹起的问题。程序按一定的频率用低电平循环扫描行线，同时检测列线的状态，一旦判断有一列为低则表示有键被按下，停止扫描并保持当前行线的状态，再读取列线的状态从而得到当前按键的键码；等待按键弹起：检测到各列线都变成高点平后，重新开始扫描过程，等待下一次按键。-Written in Verilog HDL keyboard scanner, taking into account to determine key bounce problem. Program according to a certain frequency of scan lines with low-level circulation lines, while testing out the state line, once the judge has said there is a classified as low-key is pressed, stop the scan and to maintain the current line-line state, and then read out line state to get the current keys key codes to wait for key pop-up: To detect the lines at all out into a high level after the re-start the scanning process, waiting for the next key.

该工程文件实现ARM系统中CPLD的逻辑工作，起到外围资源的逻辑地址译码功能-realization of the project document ARM system CPLD logic, external resources have address decoding logic function

针对32位MIPS微处理器中CLZ指令（对单个字高位连零进行计数）的实现电路，使用了类似于超前进位的逻辑结构。包含测试文档，以及Design Compile所用的环境和脚本。(The CLZ instruction counts the number of leading zeros in a word. The 32-bit word in the GPR rs is scanned from most-significant to least-significant bit.The number of leading zeros is counted and the result is written to the GPR rd. If all 32 bits are cleared in the GPR rs, the result written to the GPR rd is 32. )
