VLSI design of median filter
Filters are linear systems employed for removal of noise from useful
signals. Conventional IIR filters and FIR filters are highly envolved. In
general They are computional algorithms requiring definite delay between
input and the outputs. However long tailed noise such as exponentional
and laplasion distribution noise are difficult to remove using
conventional linear filters.
Median filters are a class of non linear filters having advantages
1. Capability to remove long tailed noise
2. Capability to preserve edge information
The most desirable property of median filters is that they are based on
signal “sorting and selection operations”. No Computation is involved.
Therefore, they are the most suitable for real time VLSI.
Uses
1. Image processing
2. Communication networks

VLSI based asynchronous Receiver and Transmitter
The aim of this project is to design and implement an asynchronous
receiver, transmitter using verilog hardware description language. In this
project we have used serial mode of transmission because in parallel
mode of transmission we need ‘n’ number of cable to transmit “n” bits of
data. The following features mainly distinguishes our project from other
similar devices
- full duplex operation
- standard data format
- even or odd parity
- parity error check
- over run error check
- receiver data ready
- transmitter data ready
