IIR (infinite impluse response) filters are the types of filters in which the output depends on the inputs and previous outputs. In this project we are going to implement an IIR filter in an FPGA from scratch using bilinear transform and the prewarping technique. filter(FilterName, Samples, Options) -> FilterPid = gen_filter(FilterName, Options), AggregaterPid = spawn_link(?MODULE, aggregate_filtered, IIR filter sample implementation. We use a dedicated register, multiplier -accumulator module to achieve this. As new values are fed through the input the filtered result goes out the streaming output synchronous to the input clock. This paper describes a pipelined architecture for digital image processing with a linear and adaptive median filter on FPGA (Field-programmable gate array) chips.
