TI公司的AM3359是基于高达1GHz的Sitara™ARM Cortex-A8 32位RISC处理器工业通信引擎(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:

The contains the subsystems shown in the Functional Block Diagram and a brief description of eachfollows:

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.

The PRU-ICSS is separate from the ARM core, allowing independent operation and clocking for greaterefficiency and flexibility. The PRU-ICSS enables additional peripheral interfaces and real-time protocolssuch as EtherCAT, PROFINET, EtherNet/IP, PROFIBUS, Ethernet Powerlink, Sercos, and others.

Additionally, the programmable nature of the PRU-ICSS, along with its access to pins, events and allsystem-on-chip (SoC) resources, provides flexibility in implementing fast, real-time responses, specializeddata handling operations, custom peripheral interfaces, and in offloading tasks from the other processorcores of SoC.

AM3359主要特性:

• Up to 1-GHz Sitara™ ARM® Cortex®-A8 32‑BitRISC Processor

– NEON™ SIMD Coprocessor

– 32KB of L1 Instruction and 32KB of Data CacheWith Single-Error Detection (Parity)

– 256KB of L2 Cache With Error Correcting Code(ECC) (责任编辑:admin)
