Method and apparatus for performing 2D DCT / DST / DHT by unified systolic array structure

摘要

The present invention relates to a method for performing a two-dimensional DCT / DST / DHT by a unified systolic array and an apparatus thereof, in which data is input from the right side to the left side during the execution of a one-dimensional DCT / DST / Dimensional DCT / DST / DHT in which the sum and difference of the data are calculated through the "processing element" and all the data pass through the "processing element", and the even and odd frequency components are stored in each "processing element PE" And the apparatus is extended.
