hi............im working on a project which deals with vlsi as well as 
image processing.....for this i need to store a 256X256(gray scale ) 
image and access its each and every pixel and perform an operation on 
that pixel, if the pixel is found as noisy pixel then after performing 
and removing of noise i need to feed back the new pixel value into the 
same position of the pixel......how to implement this in 
verilog...please give me some ideas..........

Typically, you will only store the lines of an image which need to be 
concurrently processed. For apps like Bayer, you will need at least 5 
delay buffers to hold enough data.

Unlike with line processing, you will need to store a full image into 
rams / brams in order to be able to do things like multipass processing 
and such.

with larger images and small fpgas, a ram controller will be required.
