A unified systolic array algorithm for discrete inverse cosine and sine transforms
Doru Florin Chiper · 2003
This paper presents a new design approach for the inverse discrete sine and cosine transforms based on a new unified systolic array algorithm that can be used to obtain VLSI array architectures with very small differences in the hardware structure for the two transforms and improved performances. This new algorithm is based on using highly regular and modular computational structures as circular correlation and can be mapped into linear systolic arrays with a small number of I/O channels and low I/O bandwidth.
