8.3 Processor Subsystems

8.3.1 Arm Cortex-A72

The device implements one dual-core Arm® Cortex®-A72 MPU, which is integrated inside the Compute Cluster,

along with other modules. The Cortex-A72 cores are general-purpose processors that can be used for running

customer applications.

The A72SS is built around the Arm Cortex-A72 MPCore (A72 cluster), which is provided by Arm and configured

by TI. It is based on the symmetric multiprocessor (SMP) architecture, and thus it delivers high performance and

optimal power management and debug capabilities.

The A72 processor is a multi-issue out-of-order superscalar execution engine with integrated L1 instruction and

data caches, compatible with Armv8-A architecture. The Armv8-A architecture brings a number of new features.

These include 64-bit data processing, extended virtual addressing and 64-bit general purpose registers.

For more information, see Dual-A72 MPU Subsystem section in Processors and Accelerators chapter in the

device TRM.

8.3.2 Arm Cortex-R5F

The MCU_ARMSS is a dual-core implementation of the Arm® Cortex®-R5F processor configured for split/lock

operation. It also includes accompanying memories (L1 caches and tightly-coupled memories), standard Arm®

CoreSight™ debug and trace architecture, integrated Vectored Interrupt Manager (VIM), ECC Aggregators, and

various wrappers for protocol conversion and address translation for easy integration into the SoC.

For more information, see Dual-R5F MCU Subsystem section in Processors and Accelerators chapter in the

device TRM.

8.3.3 DSP C71x

The TMS320C71x is the next-generation fixed and floating-point DSP platform. The C71x DSP is a new core in

the Texas Instruments' DSP family. The C71x DSP supports vector signal processing, providing significant lift in

DSP processing power over a broad range of general signal processing tasks in comparison to the C6x DSP

family. In addition, the C71x provides several specialized functions which accelerate targeted functions by more

than 30 times. Besides expanding vector processing capabilities, the new C71x core also incorporates advanced

techniques to improve control code efficiency and ease of programming such as branch prediction, protected

pipeline, precise exception and virtual memory management.

For more information, see C71x DSP Subsystem section in Processors and Accelerators chapter in the device

TRM.
