FPGA-based solutions become more common in embedded systems these days. These systems need to communicate with external world. Considering high-speed and popularity of ethernet communication, developing a reliable real-time ethernet component inside FPGA is of special value. The ethernet Mac (Media access control), sub level with in data link layer of the OSI reference model. Ethernet performance has increased from Megabits per second (M bits/s) to Gigabits per second (G bits/s) and its popularity reflects not only its status as an IEEE standard, but because the ethernet protocol has a number of features and benefits that have proved attractive to designers and engineers.
