USB2.0
- UTMI全称为 USB2.0 Transceiver Macrocell Interface,此协议是针对USB2.0的信号特点进行定义的,分为8位或16位数据接口。目的是为了减少开发商的工作量,缩短产品的设计周期,降低风险。此接口模块主要是处理物理底层的USB协议及信号,可与SIE整合设计成一专用ASIC芯片,也可独立作为PHY的收发器芯片,下以8位接口为例介绍PHY的工作原理及设计特点。 -UTMI called USB2.0 Transceiver Macrocell Interfac

communication
- QAM Radio in Matlab. Software defined radio with transmitter and receiver simulated in Matlab. 16-QAM.
UART_VHDLCodes
- 基于VHDL的异步串口收发器,在FPGA上设计Uart接收模块实现从pc接收串口数据; 在FPGA上设计Uart发送模块,把从pc接收的数据的16进制值加1再发送给PC; 设计单片机和FPGA接口模块,把接收到的数据送给单片机,并显示在LCD上 -VHDL-based asynchronous serial transceivers Uart receive module in the FPGA design from pc to receive serial data desig
SPI_verlog
- VHDL 语言实现的串转并 SPI 等等 实现-The SPI bus is a 3 wire bus that in effect links a serial shift-- register between the master and the slave . Typically both the-- master and slave have an 8 bit shift register so the combined-- register is 16 bits. Whe
