Multi-Core DSP

While image resolution in Video specific applications has increased 25-fold (from CIF (352 x 240) for VHS video to D1 (720 x480) for DVD players, and most recently to HD (1920 x 1080) for high definition video), Moore�s law has limited the capabilities of single-processor DSPs to meet the increased media processing demands, falling far short of the required performance curve.  

There have been attempts to offer this performance on large expensive FPGAs or inflexible ASICs, however, the continuously changing landscape in video standards, the dynamic nature of the requirements within this market, and the wide range of applications requiring video processing capabilities all point to cost-effective and scalable performance and flexibility as key characteristics for any viable solution for the video processing problem.

 Realizing the limitations of Moore�s law and single-core processing engines, chip architects have started a trend towards multiprocessing compute subsystems.  Cradle technology offers an innovative and award-winning approach to multiprocessing called MDSP.
