ABSTRACT:
For input signals f0-f7, by the implementing of signal processing in several stages with bit-serial form, output signals f0-f7 are obtained. For input signals f0-f7, non-two's power approximation proportions of ideal values of fixed coefficient, i.e., cos[.pi.l(2K+1)/2N] are applied. This results in asymmetrical hardware to implement a forward transform mode and an inverse transform mode. Therefore, by adding a circuit element which is employed for a forward transform mode, and by adding a circuit element which is employed for an inverse transform mode, hardware which can deal with both of forward transform and inverse transform is realized.
