The Discrete Cosine Transform (DCT)
Algorithms for the Discrete Cosine Transform (DCT) appeared in Dr Dobb's
Journal, #297, March 1999. I have translated them into PL/I, expressing
them using PL/I's fast scaled fixed-point binary facilities.
The first is the
one-dimentional 8-point algorithm.
The second is the
two-dimensional 8 x 8 (64-point) algorithm.
