Pseudo-random number generator integrating CRC (cyclic redundancy check) circuit



The invention discloses a pseudo-random number generator integrating a CRC (cyclic redundancy check) circuit and belongs to the technical field of pseudo-random number generators. The pseudo-random number generator is characterized in that on basis of the CRC circuit, a disturbing module, a status register module, a mapping circuit and a sampling circuit are added, and the pseudo-random number generator can output more reliable pseudo-random numbers, basis is provided for the development of pseudo-random number circuits, and normal execution of CRC has no effect on original functions; meanwhile, few hardware resources are added, efficacy maximization is achieved on the premise of lowest cost, and benefit of the pseudo-random number generator is improved accordingly.
