基于FPGA的数字频率计设计

FIR数字滤波器程序，采用vhdl编写，可用于FPGA电路-FIR digital filter procedure for the preparation of VHDL can be used in FPGA circuit

这是一个基本的ARM7_Core 有基本功能 但不是太完善-This is a basic ARM7_Core has the basic functions, but not too perfect

本实验实现PS/2接口与RS-232接口的数据传输， PS/2键盘上按下按键，可以通过RS-232自动传送到主机的串口调试终端上（sscom32.exe）； 并在数据接收区显示接收到的字符。 串口调试终端的设置：波特率115200，一个停止位，无校验位。-Realize this experiment, PS/2 interface with RS-232 data interface, PS/2 keyboard to press the button, through RS-232 automatic transmission to the host serial debug terminal (sscom32.exe) and data receiving display received characters. Serial debug terminal settings: 115200 baud rate, one stop bit, no parity bit.

说明：  CPU课程设计要求以FPGA开发平台为例，分析 CPU 设计的流程与仿真。 本次开发使用的硬件描述语言是 Verilog 语言，使用的指令系统是一个以 MIPS 指令集为子集的指令系统，共 22 条指令，所用的设计仿真软件Modelsim。(CPU curriculum design requires FPGA development platform as an example to analyze the process and Simulation of CPU design. The hardware description language used in this development is Verilog language, and the instruction system used is an instruction system with MIPS instruction set as a subset, with 22 instructions in total. The design simulation software Modelsim is used.)
