SH-Mobile3A

Overview

SH-Mobile3A is an application processor designed for use in high-end models of mobile phone, which incorporates the latest multimedia processing functions, including support for terrestrial digital TV broadcasts and 5-megapixel camera modules.
In addition, the SH-Mobile3A is the first offering in the SH-Mobile Series to incorporate a JPEG hardware accelerator. It realizes a maximum still photo successive capture speed, which makes possible the creation of a wide array of attractive camera applications by allowing users to snap photos in rapid succession.

Key Features

(1)	Newly developed video processing IP core with support for the video compression standard H.264 and MPEG-4 The SH-Mobile3A integrates the VPU4 (Video Processing Unit 4), a newly developed video processing IP that supports the H.264/MPEG-4 AVC (H.264) video compression standard. H.264 adopted for ISDB-T (Terrestrial Integrated Services Digital Broadcasting), a "one-segment broadcasting" system for delivering terrestrial digital TV broadcasts to portable devices such as mobile phones. The VPU4 is capable of decoding VGA size video at a rate of 30 frames per second (fps). Furthermore, it incorporates a transport stream (TS) interface that allows separate processing of video and audio data without CPU load. Moves toward the introduction of digital TV broadcasting are advancing in many countries worldwide, and the SH-Mobile3A is available to support multiple digital TV broadcasting formats for mobile phones, including DVB-H (Digital Video Broadcasting for Handheld) and DMB (Digital Multimedia Broadcasting). In addition, the VPU4 can process MPEG-4 content and provides the high-quality video processing capabilities required for applications such as video e-mail, videophone functionality, and movies.
(2)	Support for 5-megapixel class camera modules and image processing functions The SH-Mobile3A is equipped with a camera interface that supports direct connection to a 5-megapixel class camera module (the highest resolution supported by the SH-Mobile Series) and incorporates image processing functions. It can capture large volumes of image data from a high-definition camera module rapidly and process it in a variety of ways. Furthermore, by connecting the mobile phone to a TV set it is possible to display high-resolution images captured using the mobile phone's built-in camera on the TV screen. In addition, the SH-Mobile3A incorporates a hardware accelerator for processing JPEG data. It can help in the creation of attractive applications by allowing users to snap photos in rapid succession smoothly.
(3)	High-performance CPU core for speedy display processing for one-segment broadcasts The SH4AL-DSP CPU core can achieve a processing performance of 389 million instructions per second (MIPS) when operating at the maximum frequency of 216 MHz. This provides plenty of processing power to handle the browser for viewing one-segment broadcasts. And also this processing capability enables the SH-Mobile3A to easily handle parallel processing of multiple high-load applications, and operations using a general-purpose OS such as Linux involving a greater processing load than a dedicated OS.
