FPGA Implementation of a Variable Precision CORDIC Processor

چکیده
In this paper we present the FPGA implementation of a new word{serial CORDIC processor working with variable precision. It has been designed in such a way that it allows us to take advantage of the successive shifts in the coordinates involved in the CORDIC algorithm. This signiicatively reduces the total number of cycles required. Special attention has been paid to the design of the critical path to obtain an acceptable cycle time. The resulting FPGA device is able to work with a word length of 16 bits through 128 bits.

متن کاملImplementation of LU Decomposition and QR Decomposition on Parallel Processing Systems
One of the earliest attempts to implement LU Decomposition with special purpose hardware was using systolic/wavefront arrays[2]. Different proposals for the processing elements(PEs) of systolic/wavefront arrays are provided[3][4][5]. These ideas were not implemented in circuit at that time. The performance of these architectures were not quantitatively evaluated either. In 1994, E. Casseau[6] i...
