CORDIC-based window implementation to minimise area and pipeline depth

Filtering is one of the most important modules in signal processing paradigm. This study presents a field-programmable gate array implementation of various window functions using coordinate rotation digital computer (CORDIC) algorithm to minimise area-delay product. First, the authors modify the Tay...
