AM335x 微處理器基于 ARM Cortex-A8 處理器,在圖像、圖形處理、外設以及 EtherCAT 和 PROFIBUS 等工業接口選項方面得到了增強。 該器件支持高級操作系統 (HLOS)。 Linux®和 Android™可從德州儀器 (TI) 免費獲取。
AM335x 微處理器 包含 功能框圖 中顯示的子系統和以下 簡要 說明:
微處理器單元 (MPU) 子系統基于 ARM Cortex-A8 處理器, PowerVR SGX™圖形加速器子系統提供 3D 圖形加速功能以支持顯示和游戲特效。
可編程實時單元子系統和工業通信子系統 (PRU-ICSS) 與 ARM 內核彼此獨立,允許單獨操作和計時,以實現更高的效率和靈活性。PRU-ICSS 支持更多外設接口和 EtherCAT、PROFINET、EtherNet/IP、PROFIBUS、Ethernet Powerlink、Sercos 等實時協議。此外,憑借 PRU-ICSS 的可編程特性及其對引腳、事件和所有片上系統 (SoC) 資源的訪問權限,該子系統可以靈活地實現快速實時響應、專用數據處理操作以及自定義外設接口,并減輕 SoC 其他處理器內核的任務負載。
