FPGA控制的SRAM接口不分的设计

程序主要是用硬件描述语言（VHDL）实现： 4*4键盘扫描，简洁明了，通俗易懂，比较适合VHDL初学者-procedure was used in hardware description language (VHDL) to achieve : 4* 4 keyboard scan, concise, easily understood and more suitable for beginners VHDL

The red arrow showed the output became 8 when the measured temperature changed to 11°C. As shown by black arrow, the maximum output was 28. The program was run according to the proposed method.

本例设计一个码率为500kb/s，字长为8 位、帧长为128 个字、帧同步码为EB90H 的PCM 采编器。用VHDL语言实现的。(This designs a code to lead for the 500 kbs|s, the word is long for 8, the growing is synchronous code of for 128 words and for the EB90 H of PCM adopt to weave a machine.Use what VHDL language carry out. )

使用MATLAB完成CDMA系统的相关接收机，其中哈达码矩阵为128阶，仿真比特信噪比为-10DB-CDMA system using MATLAB to complete the relevant receivers, which Hadamard matrix of 128 bands, simulation-10DB-bit signal to noise ratio for

vs自定义插件开发,带卸载功能,经测试完全可用，分享给大家，可以学习！(vs custom plug-in development, with the uninstall feature, has been tested and is fully available for everyone to share, you can learn!)

4x4键盘模块。这个文件包括普通的键盘设计方案说明和相关的原程序。-4x4 keyboard module. The documents include ordinary keyboard design program descriptions and procedures related to the original.

利用verilog语言实现了SHA-1机密算法，具体算法与加密芯片ds28e01一致。(Using Verilog to achieve the SHA-1 secret algorithm, the specific algorithm is consistent with the encryption chip ds28e01.)

自编的64B/66B编码程序，下次上传解码程序。(the 64B/66B coding process is written by myself, i will upload the decoding process next time.)

设计制作一个可容纳4组参赛者的数字智力抢答器，每组设置一个抢答按键； 电路具有一第一抢答信号的鉴别和锁存的功能。在主持人将系统复位并发出抢答指令后，若参加者按抢答键，则该组指示灯亮并用组别显示抢答者的组别。此时，电路具有自锁功能，使别组的抢答开关不起作用。 设置计分电路。每组在开始时预置成6分，抢答后主持人计分，答对一次加1分。(The design can accommodate a the Entrants digital intellectual Responder, each set answer in a key circuit has a first answer in the signal to identify and latch functions. Host to the system reset and sent the answer in instruction, participants answer in key, the group of the group light and display the answer in the group. At this point, the circuit has a self-locking function does not work in other groups to answer switch. Set Scoring circuit. Preset six points each at the beginning of the answer in scoring after the host, answer time, add 1 point.)
