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
38 by both the PRU cores. The Interrupt Controller (INTC) and a CFG module are
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
51 processor cores, the memories node, an INTC node and an MDIO node represented
52 as child nodes within this PRUSS node. This node shall be a child of the
53 corresponding interconnect bus nodes or target-module nodes.
