This paper presents the basics of fast orthonormal parametrical transform called as “Constant Rotation Angle In Matrix Orthonormal (orthogonal) Transform” (CRAIMOT), briefly described in [1]. This transform can be treated as a parametrical transform or a class of transforms. Some examples of shapes of basis functions (BFs) are presented. The algorithm for generation of CRAIMOT BF is based on the product of powers of sine and cosine values for a given set of rotation angles (parameters). The CRAIMOT BFs generator is implemented as Altera’s Cyclone FPGA. A simplified block diagram and parameters of the generator is provided. Speech synthesis is aimed to be the first application of the generator.
