A 222mW H.264 Full-HD decoding application processor with x512b stacked DRAM in 40nm

A 40 nm 14-core mobile application processor with a 222 mW Full-HD H.264 video decoder and a video/audio multiprocessor is developed. It has 25 power domains. The power switch circuits realize less than 1 ¿s power-up switching while minimizing rush current. The x512b power-efficient stacked DRAM l/F...

Zusammenfassung:A 40 nm 14-core mobile application processor with a 222 mW Full-HD H.264 video decoder and a video/audio multiprocessor is developed. It has 25 power domains. The power switch circuits realize less than 1 ¿s power-up switching while minimizing rush current. The x512b power-efficient stacked DRAM l/F achieves 10.6 GB/S bandwidth.
