These accelerators have been designed using general low-energy design philosophies at the algorithmic architectural abstraction levels. The themes of these philosophies are avoiding waste and trading area performance for power and energy gains. Each core has been synthesised targeting TSMC pm TCBN90LP technology and the experimental results presented in this paper show that the proposed cores improve upon the prior art.

INTRODUCTION Whilst traditional forms of frame-based video are challenging in their own right in this context the situation becomes even worse when we look to future applications. In applications from multimedia messaging to gaming users will require functionalities that simply cannot be supported with frame-based video formats but that require access to the objects depicted in the content. Clearly this requires objectbased video compression such as that supported by MPEG-4 but this requires more complex and computationally demanding video processing. Thus whilst object-video coding has .
