Abstract This paper deals with the aspects of practical generation of basis function(s) (BF(s)) and the basic notions for orthonormal parametrical transform called as “Constant Rotation Angle In Matrix Orthonormal Transform” (CRAIMOT). The presented CRAIMOT BF generator is implemented as Altera’s Cyclone II FPGA. A simplified block diagram and parameters of the generator are provided. The generator has a parallel structure and 5 times shorter sample time in opposite to the previous implementation. The sine/cosine former of BF generator has 3 different versions – CORDIC based, the linear interpolation based, and RAM table based. The comparison of the mentioned versions is provided.
