Cortex-A9 MPU Subsystem
Two ARM Coretex-A9 MPCore
IVA-HD Subsystem
The IVA-HD subsystem is a set of video encoder/decoder hardware accelerators. It supports up to 1080p x 30 fps,
slow-motion camcorder, triple play (HD and SD capture and JPEG capture), real-time transcoding of up to 720p,
and video conferencing up to 720p.
The IVA-HD supports:
MPEG-1/2/4, Divx 5.02, H.263 P0 (encode/decode) and P3 (decode), H.264 Annex G (scalable baseline profile up
to 720p), H.264 BL/MP/HP, H.264 Annex H(partial), Stereoscopic video, JPEG(encode/decode), VC-1 SP/MP/AP,
AVS-1.0, RealVideo 8/9/10 (decode only), On2 VP6.2/VP7 (decode only)
Display Subsystem
Display controller
: Three video pipelines, one graphic pipelines, and write-back pipeline.
Two LCD outputs, One TV output.
Remote frame buffer interface (RFBI) module
Two MIPI display serial interface (DSIs)
High-definition multimedia interface (HDMI) encoder
: HDMI 1.3, HDCP 1.2, and DVI 1.0 compliant
Deep-color mode support (10-bit for up to 1080p and up to 12-bit for 1080i/720p)
NTSC/PAL video encoder
ABE (Audio Back End) Subsystem
The ABE subsystem handles audio processing for the application. It manages the audio and voice streams
between the Cortex-A9 MPU subsystem and/or DSP, and the physical interfaces.
Imaging Subsystem (ISS)
The ISS processes data coming from the image, memory, and IVA-HD subsystem. The ISS is responsible for
multimedia applications such as : camera viewfinder, video record with up to 1080p at 30 fps with digital zoom
and still image processing, such as image capture up to 16 Mp with digital zoom and rotation. The ISS supports a
pixel throughput of up to 200Mp/s. It assures good performance with sensors up to 16 Mp and more (higher
resolution can be achieved through multiple passes).
2D/3D Graphics Accelerator
The 2D/3D graphics accelerator subsystem in based on POWERVR
Technologies. The SGX can process different data types simultaneously
In addition to its processing elements, an extensive set of peripheral interfaces enables communication with all
necessary external devices.
