spi接口的eeprom模型，型号为st公司m65pxx(The eeprom model of spi interface is st company m65pxx)

ROM模块，功能在于，是创建一个简易的rom模块-rom

主要是RS-232串行接口技术并且通过了串行收发器UART的开发实例演示了接口设计的基本步骤程序-Is RS-232 serial interface technology and, through a serial UART transceiver development of interface design examples demonstrate the basic steps of the procedure

自己写的位同步实验程序参考，该算法需要发送和接收方的频率比较稳定时，可以很快地达到位同步，且十分稳定。位同步是通信技术的基础之一，希望对大家学习有所帮助。(The program is a reference used for bitsynchro writed by myself.When the both send s and receive s frequency are stable,the program can reach bitsynchro fastly.)

Frecuencymeter digital, clk frequency 10 MHZ, exhibition in 7 segments

说明：  access must be conf urr arr

说明：  ADD MOV MOVi SUB四指令cpu设计，qutartus，(Design of four-instruction CPU)

说明：  实现AXI,AXI-Lite乒乓地址的传输，AXI,AXI-Lite已经封装成内核，可直接修改后使用(Realize the transmission of table tennis address of Axi and Axi Lite. Axi and Axi Lite have been encapsulated into a kernel, which can be directly modified and used)

Use verilog language design DIGITAL-PID source

说明：  使用VHDL语言写的AVR单片机IP核， 可以直接使用，已经经过验证， 十分珍贵哦(Written in VHDL language using the AVR microcontroller IP core, can be used directly, has proven very valuable oh)
