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(yè)接口選項方面得到了增強。該器件支持高級操作系統(tǒng)(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(tǒng)和以下簡要說明:
微處理器單元(MPU)子系統(tǒng)基于ARM Cortex-A8處理器,PowerVR SGX™圖形加速器子系統(tǒng)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(tǒng)和工業(yè)通信子系統(tǒng)(PRU-ICSS)與ARM內(nèi)核彼此獨立,允許單獨操作和計時,以實現(xiàn)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,以太網(wǎng)Powerlink,Sercos等實時協(xié)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(tǒng)(SoC)資源的訪問權限,該子系統(tǒng)可以靈活地實現(xiàn)快速實時響應,專用數(shù)據(jù)處理操作以及自定義外設接口,并減輕SoC其他處理器內(nèi)核的任務負載。
