Patent ID: 8423717

Claim:
A system comprising: a main memory having a partitioning operating system stored thereon; and a multi-core processor chip operable to execute the partitioning operating system, the multi-core processor chip comprising: at least one shared cache having a plurality of ports; and a plurality of processor cores, each processor core coupled to one of the plurality of ports such that each processor core is able to access the at least one shared cache simultaneously with another of the plurality of processor cores; wherein the at least one shared cache has a plurality of address spaces that are accessible by each of the plurality of processor cores; wherein each processor core is assigned one of a unique application or a unique application task and the partitioning operating system temporally and spatially isolates each unique application and each unique application task such that each of the plurality of processor cores does not attempt to write to the same address space of the at least one shared cache at the same time as another of the plurality of processor cores; wherein at least one of the plurality of processor cores accesses one of the at least one shared cache simultaneously with another of the plurality of processor cores based on the temporal and spatial isolation of each unique application and each unique application task.
