All devices include a platform management controller (PMC) and a processing system (PS). The PMC and PS are similar from device generation to generation; both in architecture and general functionality. The type of processor cores and their cluster configurations are different across devices.
For guidance on selecting a device, refer to DS950; the integrated hardware and integrated options are identified.
The TRM describes all the possible integrated hardware options for a hardware architecture. Not all of the TRM contents applies to all devices in that generation; there are hardware options.
