RenesasMultimedia Application Processor from Renesas : Renesas Technology America announced the SH-MobileR, a sophisticated single-chip processor solution for video and digital TV enabled devices, including portable media players and VoIP video phones. The robust processor is a complete hardware implementation that supports next-generation video standards and minimizes power consumption for long battery life. By achieving 478 million instructions per second (MIPS) performance in the Dhrystone v2.1 benchmark, the device gives multimedia systems the power to deliver powerful user experiences. Built on Renesas’ SH-Mobile Series platform, the SH-MobileR device adds a new level of multimedia capability for applications beyond mobile phones.

“Deployment of digital broadcasting and broadband networks has led to the introduction of new multimedia terminals such as mobile phones, car navigation systems, and portable media players with mobile digital TV capabilities,” said Brian Davis, director of business development, Renesas Technology America, Inc. “The Renesas SH-MobileR multimedia application processor builds on the experience Renesas has gained producing chips now used in many mobile phones that support terrestrial digital TV broadcasting.”

Renesas SH-MobileR - Video processing unit
At the heart of the SH-MobileR are a hardware video processing unit that supports the video decoding and moving-image processing necessary for the reception of terrestrial digital broadcasting services, and a hardware image processing engine. The video processing unit is a very low power hardware engine for compressing and decompressing video in H.263, MPEG-4, and H.264 formats used in digital broadcasting, portable media appliance, and IP networked video telephony applications. The device minimizes total power consumption while displaying smooth moving images equivalent to that of a standard TV when decoding a compressed signal at bit rates up to 8Mbps.

5-megapixel-class camera module
To complete the host-based solution, the SH-MobileR processor integrates a camera interface that allows direct connection to a 5-megapixel-class camera module. This versatile low power hardware implementation enables a rich set of image-processing functions, including image scaling, rotate, color conversion, and blending of multiple planes of images. A built-in JPEG hardware accelerator enables the fast capture and display of JPEG images, while an on-chip 24-bit TFT color LCD controller delivers excellent image quality. An on-chip 2D graphics accelerator delivers responsive graphic user interface (GUI) performance for enhanced graphic quality. The application processor also has a video output unit for connections to National Television System Committee (NTSC) and phase-alternating line (PAL) TVs.

Renesas Application Processor
The SH-MobileR device incorporates an SH4AL-DSP CPU core that runs at speeds up to 266MHz providing 478-MIPS of performance for the parallel processing of a browser and multiple large-load applications, as well as interactions with a general-purpose operating system (OS) such as Linux. A 64-bit wide bus allows connections to data stored in external SDRAM, and an on-chip USB 2.0 function (high-speed compatible) enables fast links to PCs. The device also has a 4-Gbit NAND/AND flash memory interface with an ECC (error correction code) capability that has been improved from 3 to 4 symbols, as well as an SD memory card (SD memory/SD I/O) interface. The SD memory card interface supports an optional CPRM function, enabling the implementation of terrestrial digital broadcast recording and playback.

Accelerating Deployment of Multimedia Devices
To accelerate system designs, the SH-MobileR device is supported by a rich Linux software solution that includes open source tools and device driver code for the SH-MobileR based Solution Engine development platform. For that platform, Renesas has developed and integrated highly efficient multimedia middleware, including H.264, MPEG-4, as well as MP3, AAC (Advanced Audio Coding), G.7xx series speech codecs and echo cancellation algorithms. Certain DRM (Digital Rights Management) functions are also available for the design of audio-visual systems that protect copyrighted material. In addition, third-party partner companies are working to pre-qualify V2IP stacks, 2D and 3D graphics libraries, and other key technologies used in embedded multimedia applications that use the SH-MobileR application processor.
