布斯算法结构的 VHDL 代码

基于FPGA的JPEG解码，对开发图片解码的人有用。(FPGA-based JPEG decoding, the development of image decoding useful.)

Lights, Car light emulator for turn, stop and emergency

VHDL设计实体的基本结构 VHDL的语言要素 用VHDL实现电路设计的方法 VHDL设计流程-VHDL design entities, the basic structure of the language element of VHDL using VHDL circuit design approach to achieve VHDL design flow

说明：  实现电子密码锁的各项功能,经过编译和仿真(Electronic code lock of the function, the compiler and simulation)

说明：  用FPGA进行等精度频率和相位差测量的程序，本程序是在EPEC6Q240C8下的程序(Carried out with the FPGA such as the frequency and phase measurement precision of the procedure, this procedure was the procedure under the EPEC6Q240C8)

基于FPGA的VERILOG语言的DS18B20温度检测程序，代码自测可用(FPGA based VERILOG language DS18B20 temperature detection program, code self test available)

---实现的部分VHDL 程序如下。 　　--- elsif clk1x event and clk1x = 1 then ---if std_logic_vector(length_no) >= “0001” and std_logic_vector(length_no) <= “1001” then -----数据帧数据由接收串行数据端移位入接收移位寄存器---rsr(0) <= rxda --- rsr(7 downto 1) <= rsr(6 downto 0) --- parity <= parity xor rsr(7) --- elsif std_logic_vector(length_no) = “1010” then --- rbr <= rsr --接收移位寄存器数据进入接收缓冲器--- ...... --- end if(--- achieve some VHDL procedure is as follows.--- Elsif clk1x event and then a clk1x = s--- if td_logic_vector (length_no))

资源描述这个秒表特点是计数到59分59秒9，并且有可以让计数暂停和清零。采用了二分频，六进制和十进制组合，加上扫描电路设计而成的。

片上网络NOC基于fpga实现的，routing模块。(NOC-chip networks realized fpga-based, routing module.)

SHIFT_8REG是8位的一个具有移位功能的寄存器，每一次数据打入都会从这个寄存器的最低位打入，并相应进行向左移位。 ODD_110BREG是一个3位的备份寄存器，寄存器中存放的是奇数帧的同步头，也就是110。 EVEN_9BHREG是一个8位的备份寄存器，寄存器中存放的是偶数帧的同步头，也就是10011011。这两个寄存器的初始值在系统一开始就打入。 -SHIFT_8REG is eight with a displacement of the functional Register, Each will enter the data from the register into the lowest point, and the left shift accordingly. ODD_110BREG is a three backup Register, the Register is stored in the odd frame synchronization head, is 110. EVEN_9BHREG 8 is a backup Register, which register is kept even the first frame synchronization, is 10011011. This register the two initial value of the system into a start.
