Abstract: An implementation of digital video camera system based on ADI dual core digital signal processor ADSP-BF561 is introduced. The system can be divided into two parts——hardware and software design. The hardware design includes ADSP-BF561 and perpheral apparatus, A/D,D/A, CF card or Microdrive and so on. The software includes operating system , audio and video coding algorithm.
