Texas Instruments' ARM® Cortex™-A8 Microprocessors (MPUs)
Texas Instruments' AM3358 microprocessors, based on the ARM® Cortex™-A8, are enhanced with image graphics processing peripherals, as well as industrial interface options such as EtherCAT and PROFIBUS. The device supports the following high-level operating systems (HLOSs) that are available free of charge from TI: Linux® and Android™.
The AM335x microprocessor contains three subsystems. The first is a microprocessor unit (MPU) subsystem based on the ARM Cortex-A8 microprocessor. The second is a POWERVR SGX graphics accelerator subsystem for 3D graphics acceleration to support display and gaming effects. The third is the Programmable Real-Time Unit and Industrial Communication Subsystem (PRU-ICSS). It 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.
