The main features of the SH-MobileR2R are summarized below.
|(1)||Terrestrial digital TV broadcast support and HD video playback and recording|
|Terrestrial digital TV broadcast support is provided by the VPU5F (Video Processing Unit 5F) high-performance multi-codec video processing IP, which supports the H.264/MPEG-4 AVC*2 (abbreviated below as H.264) video compression standard used in several models of terrestrial digital broadcasts for mobile applications. In the SH-MobileR2R, the VPU5F delivers approximately 2.5 times the processing performance of the earlier SH-MobileR2, enabling encoding (recording) and decoding (playback) of HD video at 30 frames per second (fps).|
|MPEG-4 encoding/decoding and VC-1*3 decoding are also supported, providing compatibility with a wide range of video applications such as HD video cameras. It is also possible to add support for terrestrial digital broadcast formats used outside of Japan, such as DVB-H*4, which is used in Europe; DMB*5, which is used in South Korea; and CMMB*6, which is used in China.|
|(2)||Two camera module interfaces combined with VPU5F and JPU|
|There are two CEUs (Capturing Engine Unit) in the Video I/O which support up to 5M pixel image capture. The VPU5F has the flexibility to encode 1 channel of HD encode stream or 2 channels of standard-definition (720x480 pixels), abbreviated below as SD encode streams. The JPU (JPEG Processing Unit) supports the Motion JPEG encode stream. The SH-MobileR2R enables implementation of multiple video streams with different type of codec using a single chip.|
|(3)||High operating frequency of 500 MHz for high-performance processing of tasks such as simultaneous two-screen display|
|The SH-MobileR2R is built around the SH-4A high-performance CPU core, which is also incorporated in products designed for high-end built-in car navigation systems and integrates a floating-point processing unit (FPU) to improve the efficiency of video and audio processing. In the SH-MobileR2R, the maximum operating frequency of the CPU has been boosted to 500 MHz, approximately 1.3 times as fast as the existing product, SH-MobileR2. When operating at 500 MHz, general processing performance is 900 million instructions per second (MIPS) and FPU processing performance is 3.5 giga [billion] floating-point operations per second (GFLOPS). This enables parallel processing of multiple applications, such as simultaneous dual-screen display of both the car navigation system screen and a rear monitor screen, and provides ample processing power to handle a general-purpose OS such as Windows® CE*7 or Linux*8, either of which imposes a larger processing load than a custom OS would.|
|As in the existing SH-MobileR2, the SH-MobileR2R integrates on-chip 64 kilobytes of primary cache memory (32 kilobytes each for instructions and data) and a full 256 kilobytes of secondary cache memory (for both instructions and data). This contributes to faster software processing. In addition, the synchronous DRAM (SDRAM) interface supports connections to both 1.8 V DDR2 (Double Data Rate 2) and MobileDDR, which is very useful for battery-powered devices requiring low power consumption.|
|(4)||Full complement of high-performance peripheral functions for multimedia applications|
|For map rendering, the SH-MobileR2R integrates a 2-D graphics accelerator that delivers better rendering performance than the existing SH-MobileR2. This enables high-quality map rendering at high speed.|
|For audio processing, the SH-MobileR2R has a 24-bit dedicated audio DSP that supports compression formats that include Advanced Audio Coding (AAC), MP3, and Windows Media Audio (WMA)*7 with plenty of processing power to spare. Since the 24-bit dedicated audio DSP also handles the aacPlus(Advanced Audio Coding Plus)*9 audio compression format used by terrestrial digital broadcasts, this processing no longer needs to be performed by software. The resulting reduction in the CPU’s processing load is equivalent to approximately 50 MHz. This reduces power consumption, enabling TV broadcasts to be watched for a longer period of time.|
|The many on-chip peripheral functions include a 24-bit TFT color LCD controller, a USB 2.0 Host/Function module (with high-speed data transfer mode support), an ATAPI controller for connecting a hard disk or DVD drive, an SD*10 host controller with support for high-speed data transfer mode, and an Ethernet MAC (Media Access Control) controller for applications such as IP security cameras that supports connection to a 10M/100M bps (bits per second) Ethernet LAN. This full complement of high-performance functions helps to reduce the number of components in the system and to lower the overall cost while maintaining excellent performance.|
|Software solutions are provided for the total system, including video middleware supporting H.264, MPEG-4, and Windows Media Video (WMV)*9, and audio middleware supporting aacPlus.|
< Product Background >
In recent years, an increasing number of multimedia devices supporting terrestrial digital broadcasts have appeared on the market, including mobile phones, car navigation systems, and portable media players. In the car navigation system field in particular, more and more built-in car navigation systems and simple car navigation systems, such as PNDs, now provide functions supporting digital TV broadcasts. This trend is expected to continue in the future.
With its SH-Mobile Series of application processors for mobile phone systems, Renesas Technology was one of the first to deliver products with support for terrestrial digital broadcasts. The SH-Mobile Series has achieved wide adoption in many mobile phone models. The company then launched the SH-MobileR Series to broaden the field of applications beyond mobile phones and provide support for a variety of functions and configurations along with excellent flexibility. The second product in this series, the SH-MobileR2, has received a favorable response from manufacturers of terrestrial digital TV-broadcast-capable PNDs and car navigation systems. Now, in response to demand for enhanced performance and functionality, such as support for HD video, Renesas Technology is releasing the SH-MobileR2R. It is approximately 1.3 times faster than its predecessor, the SH-MobileR2, and delivers high performance, including support for HD video playback and recording, while contributing to reduced power consumption and lower system cost.
< Product Details >
The SH-MobileR2R has an on-chip SD host controller with support for high-speed data transfer mode, and the SD memory card interface supports the Content Protection for Recordable Media (CPRM) specification as an option. This makes it possible to implement playback and recording functionality for terrestrial digital TV broadcasts. There is also a 10M/100M bps Ethernet MAC controller and a two-channel camera module interface, making it easy to provide IP camera solutions at low cost.
A number of system solutions will be made available to help customers shorten development period and reduce system costs, including a reference platform incorporating the SH-MobileR2R and a graphics library that supports the functions of the 2-D graphics accelerator.
The reference platform makes it possible to study system functions, evaluate performance, and develop software efficiently. The graphics library conforms to the GDI-Sub*11 specification, which supports Windows® Automotive 5.0*12 Service Pack 2 from Microsoft Corporation, enabling customers to realize a wide variety of map rendering functions using the 2-D graphics accelerator.
There are also plans to provide support packages for IP camera devices and the like, including Linux BSPs and video codec middleware.
Two package options are available to enable more compact systems: 449-pin BGA (21 mm × 21 mm, 0.8 mm pin pitch) and 441-pin POP-compatible BGA (14 mm × 14 mm, 0.5 mm pin pitch).
Renesas Technology will continue to develop solutions for increasingly advanced and sophisticated multimedia application systems, extending the SH-Mobile Series by releasing new products that meet market demand in a timely manner.
