利用EGO1数模混合口袋实验平台上的蓝牙模块与板卡进行无线通信。使用支持蓝牙 4.0 的手机与板卡上的蓝牙模块建立连接，并且通过手机 APP 发送命令，控制 FPGA 板卡上的硬件外设。(The Bluetooth module on the EGO1 digital-analog mixed pocket experimental platform is used to communicate with the board. The Bluetooth 4.0-enabled mobile phone is used to establish a connection with the Bluetooth module on the board, and commands are sent through the mobile phone APP to control the hardware peripherals on the FPGA board.)

说明：  实现主干道交通灯显示，以状态机程序实现，并用数码管进行红绿灯倒计时的显示，内置计数模块，交通灯控制模块，数码管显示模块，并对各模块用电路图的方式进行连接。对于学习VHDL语言有所帮助。(The main road traffic light display is realized by the state machine program, and the digital tube is used to display the traffic light countdown. The counting module, the traffic light control module and the digital tube display module are built in, and each module is connected by the circuit diagram. It is helpful for learning VHDL.)

Content-addressable memory (CAM) is a special type of computer memory used in certain very-high-speed searching applications. It is also known as associative memory, associative storage, or associative array, although the last term is more often used for a programming data structure.
