TI 公司的TMDXEVM3358是AM335x ARM Cortex-A8微處理器的評估模塊,能對AM335x 處理器(AM3352, AM3354, AM3356, AM3358) 進行測試評估和開發，包括EVM基板,子板和LCD顯示模塊,主要用于游戲機外設,售貨機,家庭和工業自動化,稱重儀,消費類醫療設備,教育控制臺,打印機,高擋玩具和智能收費系統.本文介紹了AM335x 主要特性,方框圖,AM335x評估模塊(EVM)系統框圖,基板和子板方框圖,電路圖以及PCB布局圖.

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評估模塊(EVM)

The AM335x Evaluation Module (EVM) enables developers to immediately start evaluating AM335x processors (AM3352, AM3354, AM3356, AM3358) and begin building applications such as portable navigation, portable gaming and home/building automation, among others.

The AM335x general purpose EVM is a standalone test, development, and evaluation module system that enables developers to write software and develop hardware around an AM335x processor subsystem.

The main elements of the AM335x subsystem are already available on the base board of the EVM, which gives developers the basic resources needed for most general purpose type projects that encompass the AM335x as the main processor. Additional typical type peripherals are built into the EVM such as memory, sensors, LCD, Ethernet PHY, etc. so that prospective systems can be modeled quickly without significant additional hardware resources.

The System View of the AM335x General Purpose EVM consists the baseboard, daughterboard, and LCD display board stacked together and connected through standard throughhole connectors. See the pictures below of the EVM.
