Description: 扫描信号从C3 ~C0送入,信号依序为1000 ->0100 ->0010 -> 0001->1000 循环,当扫描信号为1000时,则扫描第0行中的四个按键. 扫描信号为0100时,则扫描第1行中的四个按键, 以此类推.如果有按键被按下,则R3~R0的输出信号中会有一个为1,但我们还是是无法确定哪一个键被按下,必須要从R3 ~R0 的输出信号与C3~C0的-scan signal from C0 to C3 into the signal in order of 1000-gt; 0100 - gt; 0010 - gt; 0001 - gt; 1000 cycle, when the scanning signal to 1000, then scanning 0 line of four keys. Scanning signal for 0100, then scanning resolution a line of four buttons, and so on. if a button is pressed, R3 ~ R0 the output signal will be one to one, but we are unable to confirm which a key is pressed, we must proceed from R3 ~ R0 with the output signal of C0 to C3

编写VHDL的构思:
外部接口包括: a. INPUT脚 : CLK , R3~R0.
b. OUTPUT脚 : C3~C0 , DATA3~DATA0(辨别出的按键值).
-7topic http://www.edacn.net/cgi-bin/forums.cgi forum = = 9127, under R3 R0 to the output signal will be one to one, but we are unable to confirm which a key is pressed, we must proceed from R3 to R0 the output signal C0 to C3 with the scanning signal jointly decided that button is pressed. the idea of the preparation of VHDL : external interfaces include : a. INPUT feet : CLK, R3 ~ R0. b. feet OUTPUT : C0 to C3, DATA3 ~ DATA0 (identify the key values ).

Description: 科学发现的逻辑》是波珀的代表作,也是现代科学哲学颇享盛名的主要代表作之一。本书主要讨论知识理论的两个基本问题:划界和归纳问题。作者论证科学与非科学的划界标准不是可证实性而是可证伪性,科学的方法不是归纳法而是演绎检验法。书中提出的有关科学的性质和方法以及科学知识增长的独创性论点,对科学哲学、认识论、逻辑学、方法论以及科学史、自然科学、医学、设计理论、社会科学均有影响。一些著名科学家都认为他的方法符合科学研究的实际。-the logic of scientific discovery "is a Popperian paradigm were made, as well as modern science and philosophy renowned for one of the main representatives. The book mainly discussed theoretical knowledge of the two basic issues : the demarcation and the Problem of Induction. Proof author of Science and the demarcation of standards is not sexual but could confirm Falsification, the scientific method is not induction but interpret test. The book on the nature of science and scientific method to increase knowledge and ingenuity of arguments on scientific philosophy, Epistemology, logic, methodology and the history of science, natural science, medicine, design theory, the scientific community will have an impact. Some famous scientists think his approach is consistent with the actual sci
