Abstract

Real-time processing of digital pictures from a video sequence requires several 100 Mega operations per second (MOPS) at the picture element (pel) level and a correspondingly high data rate for the transport of pels to the processing unit. A real-time video processor (RTVP) can achieve the necessary processing speed and data rate by employing an adapted architecture. By analyzing distinct algorithms from the picture coding area with special consideration of motion estimation (ME) methods, features of the algorithms have been extracted that impose requirements on the RTVP-architecture. In order to achieve the required throughput, an architecture utilizing parallel and pipelined processing and a restriction of the programmability to a set of algorithms has been derived by adapting to the algorithm requirements. This contribution focusses on the algorithm analysis and on the resulting architectural con-cepts. Some detail on an implementation of the RTVP-architecture being designed in standardcell CMOS technology is also presented.
