-description: |
- LLCC (Last Level Cache Controller) provides last level of cache memory in SoC,
- that can be shared by multiple clients. Clients here are different cores in the
- SoC, the idea is to minimize the local caches at the clients and migrate to
- common pool of memory. Cache memory is divided into partitions called slices
- which are assigned to clients. Clients can query the slice details, activate
- and deactivate them.
