Abstract: Apparatuses, systems, and methods for controlling cache allocations in a configurable combined private and shared cache in a processor-based system. The processor-based system is configured to receive a cache allocation request to allocate a line in a share cache structure, which may further include a client identification (ID). The cache allocation request and the client ID can be compared to a sub-non-uniform memory access (NUMA) (sub-NUMA) bit mask and a client allocation bit mask to generate a cache allocation vector. The sub-NUMA bit mask may have been programmed to indicate that processing cores associated with a sub-NUMA region are available, whereas processing cores associated with other sub-NUMA regions are not available, and the client allocation bit mask may have been programmed to indicate that processing cores are available.

Abstract: Aspects disclosed in the detailed description include configuring a configurable combined private and shared cache in a processor. Related processor-based systems and methods are also disclosed. A combined private and shared cache structure is configurable to select a private cache portion and a shared cache portion.

Abstract: Apparatuses, systems, and methods for configuring combined private and shared cache levels in a processor-based system. The processor-based system includes a processor that includes a plurality of processing cores each including execution circuits which are coupled to respective cache(s) and a configurable combined private and shared cache, and which may receive instructions and data on which to perform operations from the cache(s) and the combined private and shared cache. A shared cache portion of each configurable combined private and shared cache can be treated as an independently-assignable portion of the overall shared cache, which is effectively the shared cache portions of all of the processing cores. Each independently-assignable portion of the overall shared cache can be associated with a particular client running on the processor as an example. This approach can provide greater granularity of cache partitioning of a shared cache between particular clients running on a processor.
