目前以太网PHY芯片是通过总线MDC/MDIO
- 目前以太网PHY芯片是通过总线MDC/MDIO，但是基本上是通过MAC芯片直接管理的，本代码实现了通过FPGA管理PHY。即由FPGA完成MII管理,At present, Ethernet PHY chip through the bus MDC/MDIO, but basically through the direct management of MAC chip, the code through the FPGA implementation management PHY. FPGA
usb_phy.tar
- Very simple USB 1.1 PHY. Includes all the goodies: serial/parallel conversion, bit stuffing/unstuffing, NRZI encoding decoding. Uses a simplified UTMI interface. Currently doesn t do any error checking in the RX section [should probably check f
mdio
- MDIO verilog RTL代码，SOC可以通过MDIO接口来访问外部PHY等慢速外设-MDIO verilog RTL code
usb_latest.tar
- 用VHDL语言编写的USB 2.0IP核。USB 2.0的传输速率是高速率480 Mb/s，需要再外扩一个PHY。-This is a USB 2.0 compliant core，USB 2.0 allows data transfers of 480 Mb/s. Because of the high interface speed, an external PHY will be required with this core.
DX-PHY
- ddr phy design spec and example-ddr phy design spec and example!!
ofdmbaseband
- the OFDM PHY is adaptive therefore it supports multiple schemes BPSK, QPSK, 16-QAM and 64-QAM for data carriers’ modulation. The constellation diagrams are gray mapped and shows the magnitudes I and Q (In-phase and Quadrature) components of e
scrambler-wimax
