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
