LONDON – Fabless chip company Fuzhou Rockchip Electronics Co. Ltd. has started commercial production of a mixed-signal ARM9-based consumer processor using a 65-nm CMOS process from Semiconductor Manufacturing International Corp.
The RK Cayman IC includes ARM9 and DSP dual-core processors as well as numerous peripheral support circuits, including an electrophoretic display driver, and is targeted for use in MP3, MP4, e-book reader, and other digital consumer product markets, SMIC said.
The chip can support a variety of electrophoretic displays and various formats of 720-line progressive scan video playback. The chip makes use of Synopsys' USB PHY, PHY I/O and USB 2.0 intellectual property and features an OTG (On-The-Go) function in support of data exchange.
"The chip also supports CMMB, ISDB, mobile TV and other multimedia features. The camera interfaces also enable video and photo capabilities," said Feng Cheng, vice president of Rockchip (Fuzhou, China), in a statement issued by SMIC (Shanghai, China).
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
