PSEUDO-RANDOM NUMBER GENERATION CIRCUIT FOR DIGITAL SIGNAL PROCESSOR

摘要

PURPOSE:To obtain a pseudo-random number generation circuit for a digital signal processor(DSP) in which more miniaturization can be realized as the pseudo-random number generation circuit for the DSP. CONSTITUTION:In the digital signal processor provided with a serial-parallel conversion circuit 4 which converts serial signal data to parallel signal data in an input/output interface, the shift register 16 of the serial-parallel conversion circuit 4 is shared as the shift register of the pseudo-random number generation circuit 15 for white noise generation.
