13 The TI K3 family of SoCs usually have one or
14 that are used to offload some of the process
15 for achieving various system level goals.
16
17 These processor sub-systems usually contain
18 L1 and/or L2 caches/SRAMs, an Interrupt Cont
19 controller, a dedicated local power/sleep co
20 cores in the K3 SoCs are usually either a TM
21 TMS320C71x CorePac processor.

23 Each DSP Core sub-system is represented as a
24 number of required or optional properties th
25 host processor (Arm CorePac) to perform the
