Iterative-Gradient Based Complex Divider FPGA Core with Dynamic Configurability of Accuracy and Throughput

摘要

A field programmable gate array (FPGA) implementation of a highly configurable complex divider is presented, based on an iterative gradient algorithm. The proposed architecture allows to configure both the accuracy and the throughput of the division operation, which makes it suitable for diverse applications with different requirements. Results show how various throughputs can be achieved under different maximum error and iteration limit configurations. Besides, the resource occupation is considerably small, compared with previous solutions.
