Renesas Releases App Processor for Mobile Phones with Full HD Video Recording, Playback
Renesas Technology Corp has announced the SH7370, a SH-MobileHD1 application processor for mobile phones. The product is claimed to be the first in the industry to deliver Full HD (1,920 x 1,080 pixels) video recording and playback support. It supports the H.264/MPEG-4 AVC video compression standard (H.264) at Full HD video resolution with a recording/playback frame rate of 30fps.
The product incorporates two 24-bit dedicated audio DSPs to lighten the audio processing load on the CPU and reduce power consumption. This enables one DSP to handle (stereo) audio processing such as the AAC (advanced audio coding) high-quality audio compression standard and Dolby Digital Codec, with power to spare, while the other DSP handles sonic enhancement such as equalization and sample rate conversion (SRC). In addition, heavy-load processing tasks such as 5.1-channel audio can be assigned to the dual DSPs. Support for Dolby Digital and 5.1-channel audio allow interoperation with applications designed for consumer audio components.
The device includes an interface that supports connection to a transmitter microchip that implements the HDMI high-speed multimedia interface used for interconnections between AV components. This allows connection and output of Full HD resolution video to digital home electronics components such as LCD TVs or Blu-ray Disc recorders. In addition, the product can connect to an SD memory card and wireless LAN (WLAN) module, and it supports multiplexing of the MPEG2-TS (transport system) and MP4 formats.
The application processor and 512 Mbits of synchronous DRAM (SDRAM) are integrated into a single package as a system-in-package (SiP) device for greater system compactness. The device is available in a compact 10 x 11mm 407-lead BGA package.
Sample shipments of the SH7370 have begun.
