Abstract
An orthogonal transform processor comprising a rotator circuit, a look-up table and a communicator circuit. The rotator circuit performs the complex multiplications required of a rotator, the necessary coefficients are supplied by the look-up table, and the communicator circuit is charged with the task of accepting input signals, supplying the rotator with the signals necessary for each iteration, and delivering the resultant output signals. The rotator is realized with a matrix of spatially adjacent interconnected multiplier and adder modules, where each module comprises a portion of each of the multipliers necessary in the rotator.
