8 TI Programmable Real-Time Unit and Industrial Communication Subsystem
11 - Suman Anna <s-anna@ti.com>
15 The Programmable Real-Time Unit and Industrial Communication Subsystem
16 (PRU-ICSS a.k.a. PRUSS) is present on various TI SoCs such as AM335x, AM437x,
17 Keystone 66AK2G, OMAP-L138/DA850 etc. A PRUSS consists of dual 32-bit RISC
18 cores (Programmable Real-Time Units, or PRUs), shared RAM, data and
23 peripheral interfaces, fast real-time responses, or specialized data handling.
25 - an Ethernet MII_RT module with two MII ports
26 - an MDIO port to control external Ethernet PHYs
27 - an Industrial Ethernet Peripheral (IEP) to manage/generate Industrial
29 - an Enhanced Capture Module (eCAP)
30 - an Industrial Ethernet Timer with 7/9 capture and 16 compare events
31 - a 16550-compatible UART to support PROFIBUS
32 - Enhanced GPIO with async capture and serial support
34 A PRU-ICSS subsystem can have up to three shared data memories. A PRU core
36 0x0, but also has access to a secondary Data RAM (primary to the other PRU
38 by both the PRU cores. The Interrupt Controller (INTC) and a CFG module are
39 common to both the PRU cores. Each PRU core also has a private instruction
42 Various sub-modules within a PRU-ICSS subsystem are represented as individual
43 nodes and are defined using a parent-child hierarchy depending on their
48 PRU-ICSS Node
50 Each PRU-ICSS instance is represented as its own node with the individual PRU
53 corresponding interconnect bus nodes or target-module nodes.
