基于FPGA的别踩白块儿

如上图所示， Rst是低电平有效的系统复位信号，Clk是时钟信号。AB[5：0]是地址信号，DB[7：0]是数据信号，wr是低电平有效的写信号。start是启动信号。 模块中有一个64x8的双端口的存储器。系统复位结束后，可以通过AB、DB和wr信号向同步存储器写入数据。当写入64个数据后，给出一个Clk周期宽度的脉冲信号start，则系统从存储器0地址处开始读出数据，读出的8位数据从低位开始以3位为一组，每个时钟周期输出一组，即第一个时钟周期输出[2：0]位，第二个时钟周期输出[5：3]位，第三个周期输出1地址的[0]位和0地址的[7：6]位，直至将存储器中64x8数据全部输出。若最后一组不足三位，则高位补0。 (As shown above, Rst is an active-low system reset signal, Clk is a clock signal. AB [5: 0] is the address signal, DB [7: 0] is the data signal, wr write signal is active low. start is the start signal. Module in a dual port memory of 64x8. After the reset, you can write data to the synchronous memory by AB, DB and wr signals. When data is written to 64, given the width of a pulse signal Clk cycle start, the system begins to read the memory address 0, 8 data read out a low starting with three as a group, each clock outputs a set period, which is the first clock cycle of the output [2: 0] bits, the second clock cycle output [5: 3] position, the third cycle of the output of an address [0] and 0 address [7 : 6] bit, until all the data in memory 64x8 output. If the last group of less than three, the high 0s.)

这是基于verilog hdl的数字时钟源代码，能够实现时分秒的计时，可以手动进行调时与调分。(This is based on the digital clock verilog hdl source code, can be achieved when every minute of the time, you can adjust the time manually adjusting points.)

能为 sd 和 eMMC 参考，基于 verilog 的计算器计算 crc7，你会喜欢它。很好，说的源代码是太瘦了，没问题，但是你能感觉到，代码本身是很好的尽你所能 see.also，包含.exe 程序计算，其中你可以竞争。

应用背景i2cSlave is a minimalist I2C slave IP core that provides the basic framework for the implementation of custom I2C slave devices. The core provides a means to read and write up to 256 8-byte registers. These registers can be connected to the users custom logic, thus implementing a simple control and status interface.关键技术The core has up 256 registers that can be accessed via I2C. I2C write operations are used to set the register address pointer, and write the register data. I2C reads are used to read the register data. Successive data reads or writes result in data being read or written from incremental register addresses. There is no limit on how much data can be read or written in a single access, but the internal register address pointer will wrap round to 0 once it reaches 255. Note that the address pointer is not initialized at reset, and the address pointer must
