OMAP3503

应用处理器

devices are based on the enhanced OMAP 3 architecture.

The OMAP 3 architecture is designed to provide best-in-class video, image, and graphics processing sufficient to support the following:

.

Streaming video

.

Video conferencing

.

High-resolution still image

The device supports high-level operating systems HLOSs, such as:

.

Linux®

.

Windows® CE

.

Android™

This OMAP device includes state-of-the-art power-management techniques required for high-performance mobile products.

The following subsystems are part of the device:

.

Microprocessor unit MPU subsystem based on the ARM Cortex-A8 microprocessor

.

PowerVR SGX subsystem for 3D graphics acceleration to support display OMAP35 device only

.

Camera image signal processor ISP that supports multiple formats and interfacing options connected to a wide variety of image sensors

.

Display subsystem with a wide variety of features for multiple concurrent image manipulation, and a programmable interface supporting a wide variety of displays. The display subsystem also supports NTSC and PAL video out.

.

Level 3 L3 and level 4 L4 interconnects that provide high-bandwidth data transfers for multiple initiators to the internal and external memory controllers and to on-chip peripherals

The device also offers:

.

A comprehensive power- and clock-management scheme that enables high-performance, low-power operation, and ultralow-power standby features. The device also supports SmartReflex adaptative voltage control. This power-management technique for automatic control of the operating voltage of a module reduces the active power consumption.

.

Memory-stacking feature using the package-on-package POP implementation CBB and CBC packages only

OMAP35 devices are available in a 515-pin s-PBGA package CBB suffix, 515-pin s-PBGA package CBC suffix, and a 423-pin s-PBGA package CUS suffix. Some features of the CBB and CBC packages are not available in the CUS package. See Table 1-1 for package differences.
