AFDX 1G MAC IP

Description and Features

AFDX 1G MAC core is a full-featured, easy-to-use, synthesizable design that supports various Ethernet IEEE standards, ARINC 664 and supports 10/100/1000M speeds. Through its Ethernet compatibility, it provides a simple interface to a wide range of low-cost devices. AFDX 1G MAC IP is proven in FPGA environment. It can also support a variety of host bus interfaces for easy adoption into any design architecture - AHB, AHB-Lite, APB, AXI, AXI-Lite, Tilelink, OCP, VCI, Avalon, PLB, Wishbone or custom buses. AFDX 1G MAC IP is supported natively in Verilog and VHDL.
