VLSI array processors' block implementation of IIR digital filters

Implementation of Matrix Decomposition Structures of 2-d Digital Filters via Vlsi Array Processors*

This paper describes an implementation of 2-D FIR and IIR linear digital filters via VLSI array processors. The underlying realization structures are based on the matrix decomposition approach. The 2-D concurrent processing is used in order to implement the row and column delays within the cycle time. A high degree of concurrency is achieved by exploiting the pipelining of the array processors ...

Implementation of Iir Digital Filters in Fpga

The problem of mapping data flow graphs (DFGs) of infinite impulse responce (IIR) filtering algorithms into application specific structure is considered. Methods of optimization of DFGs are considered for the purpose of finding IIR filter structures with the high throughput and hardware utilization. Optimization method is proposed which takes into account structural properties of FPGA, minimize...

Pipelining of cordic based IIR digital filters

Cordic based IIR digital lters possess desirable properties for VLSI implementation such as local connection, regularity, and good nite word-length behavior, but can't be pipelined to ner levels (such as bit or multi-bit levels) due to the presence of feedback loops. In this paper, a pipelining method for the cordic based IIR digital lters is proposed using the constrained lter design methods a...
