A Comparative Study of Pipelining Techniques for Recursive Filter Implemented in FPGA
نویسنده
چکیده
This paper presents different pipelining approach for higher order recursive digital filter. The performance of the filter is increased by pipelining the filter. Clustered look-ahead, scattered look-ahead pipelining methods and implementation of IIR filter in FPGA are analyzed. Clustered look-ahead pipeline is not always stable. To achieve a stable pipeline filter scattered look-ahead pipelining is used. The second order all pole recursive filter is considered and 3-level pipelined transfer function is obtained using clustered look-ahead and scattered look-ahead pipelining techniques. The filter is implemented in direct form-I structure.

متن کاملDistance Dependent Localization Approach in Oil Reservoir History Matching: A Comparative Study
To perform any economic management of a petroleum reservoir in real time, a predictable and/or updateable model of reservoir along with uncertainty estimation ability is required. One relatively recent method is a sequential Monte Carlo implementation of the Kalman filter: the Ensemble Kalman Filter (EnKF). The EnKF not only estimate uncertain parameters but also provide a recursive estimat...

This paper presents an efficient architecture for FIR filter using multi hierarchy pipelining. By choosing inner clock frequency several times more than the input sampling frequency multiply and accumulate components can be shared and hence the area and delay are optimized. An N tap FIR filter can be divided into N/M groups and two hierarchies of pipelining stages are inserted between N/M group...
متن کاملAn Efficient LUT Design on FPGA for Memory-Based Multiplication
An efficient Lookup Table (LUT) design for memory-based multiplier is proposed. This multiplier can be preferred in DSP computation where one of the inputs, which is filter coefficient to the multiplier, is fixed. In this design, all possible product terms of input multiplicand with the fixed coefficient are stored directly in memory. In contrast to an earlier proposition Odd Multiple Storage ...
