AM3359 BeagleBone開源開發(fā)板采用TI公司的低成本基于ARM Cortex-A8的500MHz-720MHz的處理器AM3359, 用來工程開發(fā),演示或評(píng)估處理器,主要用在游戲外設(shè),銷售機(jī),家庭和工業(yè)自動(dòng)化,稱重儀,消費(fèi)類醫(yī)療設(shè)備, 智能收費(fèi)系統(tǒng)和教育控制臺(tái),打印機(jī)以及高檔玩具.本文介紹了AM335x主要特性,方框圖以及AM335x BeagleBone開源開發(fā)板主要特性,方框圖,電路圖和材料清單.
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.

AM335x BeagleBone開源開發(fā)板
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.
