Today's cellular phones must support full high-definition (full-HD) video in multiple video formats, such as H.264 and MPEG-2/-4, with low power consumption. Full-HD video processing requires six times the data bandwidth and is more computationally intensive than conventional standard-definition (SD) video. The trade-off between flexibility, performance and power consumption is a key focus of video-codec...
A video-size-scalable H.264 high-profile codec including 19 application-specific CPUs for extensibility to multiple standards has been fabricated in 65 nm CMOS. With two parallel pipelines for macroblock processing, the codec consumed 256 mW in real-time encoding of 40 Mbp full-HDs (1080p30) video at an operating frequency of 162 MHz.
To solve recent pressing issues regarding satisfying numerous video codec standards and supporting ldquofull-high-definitionrdquo (full-HD) (i.e., 1920 pixels by 1080 lines) video on different consumer devices, a multi-standard CODEC IP based on a heterogeneous multiprocessor architecture was developed. To achieve satisfactory performance with low power consumption, operation-specific processors were...
