Multi-core heterogeneous system and its hardware resource management method

Abstract

Provided are an asymmetric multiprocessing system and a method for managing a hardware resource thereof. The method for managing a hardware resource of the asymmetric multiprocessing system comprises: registering, by a master core, a common hardware resource required for an operation of each mode (S10); reading and managing the common hardware resource (S12); and receiving, from a slave core corresponding to one mode, information associated with a hardware resource required for an operation of the mode, and allocating, according to registration information corresponding to the mode, to the slave core a common hardware resource required for the operation of the mode (S14). The method for managing a hardware resource of the asymmetric multiprocessing system can dynamically allocate common hardware resources required by respective modes according to resource allocation requirements of the respective modes, thereby ensuring flexible use of the common hardware resources of the asymmetric multiprocessing system, and preventing waste of the common hardware resources.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a multi-core heterogeneous system and a method for managing hardware resources thereof. Background technique [0002] The current multi-core processing system mainly has two structures: one is SMP (Symmetric Multi-Processing, symmetrical isomorphic multi-core processing system), and the other is AMP (Asymmetric Multi-Processing, heterogeneous multi-core processing system). [0003] In the field of wireless communication, heterogeneous multi-core processing systems are relatively common. For example, baseband chips need to process baseband signals. Baseband signal processing includes L1 (physical layer), L2 (MAC, RLC, PDCP and other sublayers) and L3 ( Such as RRC) and other protocol function layers, usually the baseband chip should use a special processor or accelerator, and also have a general-purpose core for base station management and L2 and L3 functions of the...

Problems solved by technology

[0004] As a common communication device in the wireless communication field, wireless base stations include single-standard base stations and multi-standard (commonly used standards for base stations include GSM, UMTS, CDMA, LTE_FDD, LTE_TDD, etc.) base stations. However, in the prior art, the baseband of wireless base stations In order to expand its capacity, the chip will adopt a heterogeneous multi-core processing system, and the baseband chip of the existing wireless base station has fixed hardware resources for each standard (hardware resources include but are not limited to network port queues, counters, shared memory , inter-core interrupts, etc.), hardware resources cannot be shared, thus causing a waste of hardware resources
