1.1 Overview
The OMAP4460 high-performance multimedia application device is based on enhanced OMAP™
architecture and uses 45-nm technology.
• The architecture is designed to provide best-in-class video, image, and graphics processing for 2.5/3G
wireless terminals, high-performance personal digital assistants (PDAs). For that purpose, the device
supports the following functions:
– Streaming video up to full high definition (HD) (1920 × 1080 p, 30 fps)
– 2-dimensional (2D)/3-dimensional (3D) mobile gaming
– Video conferencing
– High-resolution still image (up to 16 Mp)
• The device supports high-level operating systems (OSs) such as:
– Linux®
– Palm OS™
– Symbian OS™
– Windows™ CE, WinMobile™
• The device is composed of the following subsystems:
– Cortex™-A9 microprocessor unit (MPU) subsystem, including two ARM® Cortex-A9 cores
– Digital signal processor (DSP) subsystem
– Image and video accelerator high-definition (IVA-HD) subsystem
– Cortex™-M3 MPU subsystem, including two ARM Cortex-M3 microprocessors
– Display subsystem
– Audio back-end (ABE) subsystem
– Imaging subsystem (ISS), consisting of image signal processor (ISP) and still image coprocessor
(SIMCOP) block
– 2D/3D graphic accelerator (SGX) subsystem
– Emulation (EMU) subsystem
• The device includes state-of-art power-management techniques required for high-performance mobile
products.
• Comprehensive power management is integrated into the device.
• The device also integrates:
