The cycle accurate DSP model design based on SystemC

With the development of the DSP design technique, the DSP structure becomes more and more complex and the speed of RTL simulation is slower and slower. In this paper, a cycle accurate DSP model based on SystemC is designed to speed up the simulation. Through the simulation of g.721 audio encoding program and the IDCT that is the main part of image processing, the time of cycle accurate DSP model simulation is about one minute and ten seconds, however the time of RTL simulation is about thirty minutes and five minutes.
