[原创] TI AM3359工业通信引擎(ICE)开发方案TIDEP0001

TI公司的AM3359是基于高达1GHz的Sitara™ARM Cortex-A8 32位RISC处理器的工业通信引擎(ICE),具有增强的图像和图形处理,外设和工业接口选择如EtherCAT和PROFIBUS,支持高等级操作系统(HLOS).还包含NEON™ SIMD协处理器,集成了32KB L1指令和32KB数据缓存,256KB ECC L2缓存,176KB引导ROM,64KB专用RAM,仿真和调试-JTAG,多达128个中断请求的中断控制器,64KB通用片上存储器控制器(OCMC)RAM,主要用在游戏外设,家庭和工业自动化,消费类医疗设备,打印机和智能收费系统.本文介绍了AM3359主要特性,功能框图以及EtherCAT通信开发平台TIDEP0001主要特性,电路图和材料清单.

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). Processor SDK Linux® and TI-RTOS are availablefree of charge from TI.

The AM335x microprocessor contains the subsystems shown in the Functional Block Diagram and a briefdescription of each follows:
