AM335x微处理器基于ARM Cortex-A8处理器,在图像,图形处理,外设以及EtherCAT和PROFIBUS等工业接口选项方面得到了增强。该器件支持高级操作系统(HLOS).Linux ®和Android™可从德州仪器(TI)免费获取。
AM335x微处理器包含功能框图中显示的子系统和以下简要说明:
微处理器单元(MPU)子系统基于ARM Cortex-A8处理器,PowerVR SGX™图形加速器子系统提供3D图形加速功能以支持显示和游戏特效。
可编程实时单元子系统和工业通信子系统(PRU-ICSS)与ARM内核彼此独立,允许单独操作和计时,以实现更高的效率和灵活性.PRU-ICSS支持更多外设接口和EtherCAT,PROFINET,EtherNet /IP,PROFIBUS,以太网Powerlink,Sercos等实时协议。此外,凭借PRU-ICSS的可编程特性及其对引脚,事件和所有片上系统(SoC)资源的访问权限,该子系统可以灵活地实现快速实时响应,专用数据处理操作以及自定义外设接口,并减轻SoC其他处理器内核的任务负载。
