FPGA implementation of a image filtering

Components

Filter Bank

filter bank chooser

Multiplier (with adder)

Efficient adder

Fifo_buffer_3

Cache memory

Zipper

Module zipper takes the filter output and trim it down to the range 0...255.

Controller

This module provides control signals as shown in the picture

This is a complex module that do a lot of calculations

Enabler

This module enable the controller after some time
