说明：  Collection of Ethernet-related components for gigabit, 10G, and 25G packet processing (8 bit and 64 bit datapaths). Includes modules for handling Ethernet frames as well as IP, UDP, and ARP and the components for constructing a complete UDP/IP stack. Includes MAC modules for gigabit and 10G/25G, a 10G/25G PCS/PMA PHY module, and a 10G/25G combination MAC/PCS/PMA module. Includes various PTP related components for implementing systems that require precise time synchronization. Also includes full MyHDL testbench with intelligent bus cosimulation endpoints.

CPLD的VerilogHDL总线代码,在EPM7128SLC84-10+Quartus4平台上运行通过.-CPLD bus Verilog HDL code, the PLD-10 Quartus4 platform to run through.

用VHDL编写的EPP通信协议，可以同时收发字节-EPP written in VHDL, communication protocol, you can also send and receive bytes

说明：  高斯最小频移键控（Gaussian Filtered Minimum Shift Keying），这是GSM系统采用的调制方式。数字调制解调技术是数字蜂窝移动通信系统空中接口的重要组成部分。GMSK调制是在MSK（最小频移键控）调制器之前插入高斯低通预调制滤波器这样一种调制方式。GMSK提高了数字移动通信的频谱利用率和通信质量。(Gauss Filtered Minimum Shift Keying is a modulation method used in GSM system. Digital modem technology is an important part of air interface of digital cellular mobile communication system. GMSK modulation is a method of inserting a Gaussian low-pass pre-modulation filter before the MSK (minimum frequency shift keying) modulator. GMSK improves the spectrum utilization and communication quality of digital mobile communication.)
