Pipelined Cordic Based Cascade Orthogonal IIRDigital
Cordic based cascade orthogonal IIR digital lters possess desirable properties for VLSI implementations such as local connection, regularity, absence of limit cycle and overrow oscillations, and good nite word-length behavior. However, the achievable sample rate of these lters is limited, since these structures can't be pipelined at ner levels (such as bit or multi-bit level) due to the presenc...
متن کاملPipelined CORDIC based QRD-MVDR adaptive beamforming
Cordic based QRD-MVDR adaptive beamforming algorithms possess desirable properties for VLSI implementation such as regularity and good nite-word length behavior. But this algorithm su ers from speed limitation constraint due to the presence of recursive operations in the algorithm. In this paper, a ne-grain pipelined Cordic based QRD-MVDR adaptive beamforming algorithm is developed using the ma...
متن کاملCordic based parallel/pipelined architecture for the Hough transform
We present the design of parallel architectures for the computation of the Hough transform based on application-specific CORDIC processors. The design of the circular CORDIC in rotation mode is simplified by the a priori knowledge of the angles participating in the transform and a high throughput is obtained through a pipelined design combined with the use of redundant arithmetic (carry save ad...
متن کاملPipelined Cordic Based Qrd-rls Adaptive Filtering Using Matrix Lookahead
In this paper, the matrix lookahead transformation is developed to achieve ne-grain pipelining for Cordic based QRD-RLS adaptive ltering algorithm. Various implementation styles are proposed. They include pipelining, block processing, and incremental block processing. The proposed architectures can operate at arbitrarily high sample rates, and consist of only Givens and a few Gaussian rotations...
متن کاملDDS Based on Pipelined CORDIC Algorithm with Communication System
– The theoretical analysis gives an overview of the functioning of DDS, especially with respect to noise and spurs. Different spur reduction techniques are studied in detail. Four ICs, which were the circuit implementations of the DDS, were designed. One programmable logic device implementation of the CORDIC based quadrature amplitude modulation (QAM) modulator was designed with a separate D/A ...
