Abstract

The invention provides a multicore processor-oriented internal memory management system. The system is characterized by dividing progress memory access behaviors into a static attribute and a dynamic attribute, wherein the static attribute is used for describing general internal memory demand behaviors (sing-page or burst-mode requests) represented by progresses; the dynamic attribute is used for describing the characteristics represented by the progresses for internal memory requirements in the life cycle active processes of the progresses; and on the basis of analysis carried out on the static attribute and the dynamic attribute, internal memory operation modules in and between the progresses are imported. The system can be used for effectively improving the system distribution efficiency and effectively reducing the competition of internal memory resource locks between multiple cores.

Description

technical field [0001] The present application relates to the technical field of multi-core processor memory management, in particular, to a multi-core processor-oriented memory management system and a memory management method thereof. Background technique [0002] A multi-core processor refers to the integration of two or more complete computing engines (cores) in one processor. Samsung, Freescale, TI and other semiconductor manufacturers have launched dual-core and quad-core processors for smart phone platforms. Compared with single-core systems, multi-core systems have more stringent requirements for memory bandwidth. The CMP multi-core system with shared memory occupies a dominant position in the field of smart phones, and multi-core processors further intensify the competition for memory resources. Android adopts a centralized partner allocation algorithm to process each memory resource request and release operation according to the principle of FCFS. [0003] The bu...
