Analysis of different types of code converters using xilinx

The global technology has evolved drastically and machines are playing a major part in the development. Everything is getting digital in this fast moving world. It will not be wrong to say that human beings are co - existing with machines. However in order to operate a machine, we need a language or a code which is machine readable and acceptable. This is where we introduce the concept of coding. Coding is a process to convert the input information in a machine-readable language. It primarily protects the information from getting stolen or interrupted and makes the data user friendly. It is also done to make hardware implementation feasible.Many complicated operations take place in a machine or any performing peripheral which requires certain specific codes on which it will specifically work, code conversion is required in situations like this. This paper deals with the designing of 4-bit binary to gray code converter, 4 bit binary- to -gray, 4- bit BCD-to-excess 3 and 4 -bit gray to binary code converters by applying data flow modelling. Xilinx ISE software is used for testing the code converter.
