[原创] TI AM3359并行冗余协议(PRP)以太网参考设计

TI公司的AM3359是基于ARM Cortex-A8处理器的微处理器,具有增强的图像图形处理以及外设和工业接口选择如EtherCAT和PROFIBUS,器件支持高级操作系统(HLOS).工作频率高达1GHz,NEON™ SIMD协处理器,集成了32KB L1指令和32KB数据缓存,带误差修正码(ECC)的256KB L2缓存,176KB引导ROM,64KB专用RAM以及中断控制器.主要用在游戏外设,家庭和工业自动化,消费类医疗电器,打印机,智能玩具系统,连接的售货机和称重仪.本文介绍了AM3359主要特性和功能框图,以及用于变电站自动化的并行冗余协议(PRP)以太网参考设计TIDEP0054主要特性,框图,电路图,材料清单和PCB设计图.

The AM335x microprocessors, based on the ARM Cortex-A8 processor, are enhanced with image,graphics processing, peripherals and industrial interface options such as EtherCAT and PROFIBUS. Thedevices support high-level operating systems (HLOS). Linux® and Android™ are available free of chargefrom TI.

The AM335x microprocessor contain the subsystems sand a brief description of each follows:

The microprocessor unit (MPU) subsystem is based on the ARM Cortex-A8 processor and the PowerVRSGX™ Graphics Accelerator subsystem provides 3D graphics acceleration to support display and gamingeffects.
