AM3359 BeagleBone开源开发板采用TI公司的低成本基于ARM Cortex A8的500MHz-720MHz的处理器AM3359, 用来工程开发,演示或评估处理器,主要用在游戏外设,销售机,家庭和工业自动化,称重仪,消费类医疗设备, 智能收费系统和教育控制台,打印机以及高档玩具.本文介绍了AM335x主要特性,方框图以及AM335x BeagleBone开源开发板主要特性,方框图,电路图和材料清单.

The AM335x microprocessors, based on the ARM Cortex-A8, are enhanced with image, graphics processing, peripherals and industrial interface options such as EtherCAT and PROFIBUS. The device supports the following high-level operating systems (HLOSs) that are available free of charge from TI:

• Linux®

• Windows® CE

• Android™

The AM335x microrocessor contains these subsystems:

• Microprocessor unit (MPU) subsystem based on the ARM Cortex-A8 microprocessor.

• POWERVR SGX™ Graphics Accelerator subsystem for 3D graphics acceleration to support display and gaming effects.

• Programmable Real-Time Unit Subsystem (PRUSS) enables the user to create a variety of digital resources beyond native peripherals of the device. In addition, the PRUSS is separate from the ARM core. This allows independent operation and clocking to give the device greater flexibility in complex system solutions.

The BeagleBone is the latest addition to the BeagleBoard.org family and like its’ predecessors, is designed to address the Open Source Community, early adopters, and anyone interested in a low cost ARM Cortex A8 based processor. It has been equipped with a minimum set of features to allow the user to experience the power of the processor and is not intended as a full development platform as many of the features and interfaces supplied by the processor are not accessible from the BeagleBone via onboard support of some interfaces.
