Abstract
The COordinate Rotation DIgital Computer (CORDIC) algorithm is an efficient algorithm to calculate the iteratively phase and magnitude or the vector rotations in linear, hyperbolic and circular coordinate system. The existing CORDIC method takes less clock frequency with high delay. To overcome this problem, a new version of updated parallel and pipelined architecture is designed without degrading the performance. It provides highest maximum frequency with less delay by splitting the critical path into several smaller delay paths with enhanced circuit processing time. The designed architecture in this study can be used in navigation application. This method is implemented in the Xilinx ISE tool.
Highlights
In June 1956, the COordinate Rotation DIgital Computer (CORDIC) algorithm and a computerized design for executing CORDIC algorithm introduced to Convair management as a technical report
Sine and Cosine waveforms are directly given by the CORDIC algorithm which acts as a quadrature phase-to-amplitude converter [13]
Since real time data acquisition is the need of the hour, this method has enormous scope in real time processing
Summary
In June 1956, the CORDIC algorithm and a computerized design for executing CORDIC algorithm introduced to Convair management as a technical report. During the preparation of the report, it was realized by VOLDER that the same computerized design could be comfortably alter to generate, logarithmic functions, hyperbolic coordinate rotation and exponential expressions. In [1] different characteristics of CORDIC algorithm are described. It is implemented in the Field Programmable Gate Array (FPGA) processor. In [2] CORDIC rotator algorithm is described by setting the scale factor constant in order to perform the iteration.
