IDCT-M is a medium speed 1D IDCT core
-- it can accept a continous stream of 12-bit input WORDs at a rate of
-- 1 bit/ck cycle, operating at 50MHz speed, it can process MP@ML MPEG video
-- the core is 100％ synthesizable
This function obtains a unitary matrix Q such that: d=diag(Q *diag(lmd)*Q).
In other WORDs, it gives a way to generate a matrix with given eigenvalues and diagonal elements.
