Features

  • The SH-MobileR incorporates a VPU4 (Video Processing Unit 4) image processing IP supporting the H.264/MPEG-4 AVC moving-image compression standard used for digital broadcasting in various regions of the world, and it enables 30 fps (frame per second) encoding and decoding of VGA-size moving images.
  • The application processor incorporates a camera interface that allows direct connection to a 5-megapixel-class camera module, together with image processing functions, and can perform high-speed capture of large-volume image data from a high-definition camera, and versatile image processing.
  • An on-chip 2D graphics accelerator improves rendering performance, and can allow fast and sophisticated rendering on the complex GUI (Graphical User Interface) display of a device's operation menu screen, for example.
  • The high-performance SH4AL-DSP CPU core realizes the achievement of 478 MIPS (million instructions per second) at a maximum operating frequency of 266 MHz, providing ample power for parallel processing of a browser and multiple large-load applications, as well as operation by a general-purpose OS such as Linux that imposes a greater processing load than a dedicated OS.
