摘要
A memory access method in a multicore processor integrated circuit (IC) is provided. The method comprises partitioning local memory on the IC into a plurality of memory regions wherein each memory region comprises one or more memory segments and assigning each memory region to one or more processing entities or applications wherein each processing entity comprises a processor core or a processing device that is under the control of a processor core and wherein the application is capable of being performed by one of the processing entities. The method further comprises monitoring, with each processing entity, the usage of each memory segment in each region assigned to the processing entity and assigned to the applications performed by the processing entity and swapping the data in a memory segment from a memory region experiencing a miss for desired data when the miss causes a data access with external memory.
