TLDR
This paper has implemented a Shannon-fano algorithm for data compression through VHDL coding, which is also used in an implode compression method which are used in zip file or .rar format.Abstract:
In digital communication while transmit the data it is well desire that the transmitting data bits should be as minimum as possible, so to compress the data there are several technique used In this paper we have implemented a Shannon-fano algorithm for data compression through VHDL coding Using VHDL implementation we can easily observe that how many bits we can save or how much data gets compressed during transmission, and we can also see the encoding of the respective symbol of transmit data In the field of data compression the Shannon-fano algorithm is used, this algorithm is also used in an implode compression method which are used in zip file or rar format To implement this algorithm in VHDL we use ModelSim SE 64 simulators and to synthesize these code Quartus-II tool has been usedread more
