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)。处理器 SDK Linux®和 TI-RTOS 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,并简要介绍了 简要 说明:
包含功能框图中显示的子系统,并简要介绍了 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 支持附加外设接口以及 EtherCAT、PROFINET、EtherNet/IP、PROFIBUS、以太网 POWERLINK、串行实时通信协议 (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。
