2/11/2005 - Renesas Technology Corp. announced the SH-Mobile3A (SH73380), a new edition to the SH-Mobile series of mobile phone application processors. The device offers the latest multimedia processing features, including support for terrestrial digital TV broadcasts and 5-megapixel camera modules, and a JPEG hardware accelerator for still images. This makes it ideal for use in high-end mobile phones.
The SH-Mobile3A incorporates the newly developed VPU4 video processing IP. This provides high speed processing support for the video compression standards H.264 adopted for ISDB-T, a 'one-segment broadcasting' system for delivering terrestrial digital TV broadcasts to portable devices, and MPEG-4 used for movie and videophone applications. The VPU4 is capable of decoding VGA size video at a rate of 30 frames/second (f/s). Furthermore it incorporates a transport stream interface that allows separate processing of video and audio data without CPU load. The device can also support multiple digital TV broadcasting formats for mobile phones, including DVB-H and DMB.
The VPU4 incorporates 7-stage pipeline processing technology that reduces power consumption either through the use of lower clock frequencies or through dynamic variation of the clock numbers of the individual stages. As a result, current consumption by the IP core while operating at 66 MHz is only approximately 36 mA when decoding VGA size video at a rate of 30 f/s.
The SH-Mobile3A is equipped with a camera interface that supports direct connection to a 5-megapixel camera module (the highest resolution supported by the SH-Mobile series) and incorporates image processing functions. The interface allows large volumes of image data to be captured and displayed with a variety of options, including digital zoom and overlay using on-screen display (OSD) and hardware cursor (HWC) functions, for example. The SH-Mobile3A also includes a video output unit compatible with NTSC and PAL, allowing the mobile phone to be connected to a TV to display high-resolution images captured using the mobile phone's built-in camera.
The processor is the first device in the SH-Mobile series to incorporate a newly developed JPEG hardware accelerator. This realises a maximum still photo successive capture speed of 0.02 seconds/photo or better for VGA size and 0.1 seconds/photo or better for SXGA size. This makes the creation of a wide range of attractive camera applications possible by allowing users to take photos in rapid succession.
The SH-Mobile3A is based on the SH4AL-DSP CPU core that offers a processing performance of 389 MIPS at a maximum operating frequency of 216 MHz. This gives a performance by frequency unit of 1.8 MIPS/MHz, enough to handle a browser for viewing one-segment broadcasts. This capability also enables the device to handle parallel processing of multiple high load applications and operations using a general purpose OS such as Linux for a greater processing load than a dedicated OS.
Additionally, the SH-Mobile3A offers a variety of peripheral functions ideal for mobile phone systems, including an LCD controller compatible with TFT colour LCD panels and a sound interface. The device is available in a 409-pin CSP package (12 mm x 12 mm x 1.4 mm, 0.5 mm pin pitch). Sample shipments will begin in April 2005.
