Implementation of 8B/10B encoder-decoder for Gigabit Ethernet Frame

This paper describe a byte oriented transmission code and its hardware implementation with elaborating a method for implementation of the DC-balanced 8B/10B coding using a very fast FPGA from Spartan family. This code is particularly well suited for high-speed local area networks. This technique can be used by other high speed buses such as PCI Express, IEEE 1394b, Serial ATA, SAS, Fiber channel, SSA. Gigabit Ethernet INFIBAND, XAUI, Serial Rapid IO, uses the same coding module. Using the Look-up Table and memory with fast technique made this design efficient to be implemented. A very simple implementation of the code has been accomplished by the partitioning of the coder into 5B/6B and 3B/4B subordinates coders. For increasing its performance more RTL logic is required.
