Abstract
System-in-silicon (SiS) is a multi-chip architecture to realize wide bandwidth communication between logic and memory with low power. The application of SiS to H.264/AVC motion estimation is presented. DRAM is integrated with 23.1 Gb/s bandwidth and 1.6pJ/b data transfer efficiency, realizing real-time 1080HDTV processing with 263.1GB/s. The authors present a system-in-silicon architecture with 1024b inter-chip bus to provide high-bandwidth low-power connectivity between logic and memory. The highly parallel architecture also allows low frequency (25MHz) operation while achieving real-time motion estimation for 1080HDTV. The solution achieves the required 23.1 Gb/s bandwidth and associated processing for motion estimation at a power level of 190mWKeywords
