The Programmable Real-time Unit Subsystem (PRUSS) consists of dual 32-bit RISC cores (the PRUs), shared data, instruction memories, internal peripheral modules, and an interrupt controller (INTC). The programmable nature of the PRU cores, along with their access to pins, events and all device 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 the device.

Industrial Communication Subsystem features including Ethernet (MII signals and MDIO signals are not pinned out) are not supported.

Devices offering the PRUSS capability include AM62x.
