The RPU subsystem includes the Cortex-R5F MPCore processors with their tightly-coupled memories (TCM), and OCM memory. The RPU also has a direct interconnect to the accelerator RAM (XRAM, if present) that can be partitioned and shared in some devices with logic in the PL. The PS LPD interconnect includes the RPU MPCore, OCM, PSM controller, and the I/O peripherals (IOP). The LPD has several connections to I/O pins.
The following figure shows the system interconnect diagram.
