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. The
devices support high-level operating systems (HLOS). Processor SDK Linux® and TI-RTOS are available
free of charge from TI.
The AM335x microprocessor contains the subsystems shown in the Functional Block Diagram and a brief
description of each follows:
The contains the subsystems shown in the Functional Block Diagram and a brief description of each
follows:
The microprocessor unit (MPU) subsystem is based on the ARM Cortex-A8 processor and the PowerVR
SGX™ Graphics Accelerator subsystem provides 3D graphics acceleration to support display and gaming
effects.
The PRU-ICSS is separate from the ARM core, allowing independent operation and clocking for greater
efficiency and flexibility. The PRU-ICSS enables additional peripheral interfaces and real-time protocols
such 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 all
system-on-chip (SoC) resources, provides flexibility in implementing fast, real-time responses, specialized
data handling operations, custom peripheral interfaces, and in offloading tasks from the other processor
cores of SoC.
