PRU Block Diagram

The Programmable Real-Time Unit Subsystem and Industrial Communication SubSystem (PRU-ICSS) consists of dual 32-bit RISC cores (Programmable Real-Time Units, or PRUs), data and instruction memories, internal peripheral modules, and an interrupt controller (INTC). The programmable nature of the PRU-ICSS, along with their access to pins, events and all 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 the system-on-chip (SoC).

Overview[edit]

The PRU-ICSS hardware can be used for two categories of applications:

This wiki page serves as a hub for PRU subsystem collateral and related resources including software user guides, application notes, training modules, and FAQs. A block diagram of the full PRU-ICSS is shown above.
