A shared resource arbitration method and device

Abstract

The invention discloses a method and device for arbitration of shared sources. The method comprises the steps that a service resource request linked list is received, the service resource request linked list is checked, and the service resource request linked list which passes the checking is sent to a to-be-processed service queue, wherein the service resource request linked list comprises resource request units; an arbitration strategy is determined according to acquired use situations of the shared resources and resource demands of the service resource request linked list; and the resource request units of the service resource request linked list in the to-be-processed service queue are regrouped according to the arbitration strategy, the regrouped resource request units are sent to the arbitrated service queue, and the shared resources are distributed according to the arbitrated service queue. According to the invention, the resources can be distributed rationally during multi-service concurrent operations.

Description

technical field [0001] The invention relates to the technical field of multi-service concurrent operation, in particular to a shared resource arbitration method and device. Background technique [0002] With the development of technology, the integration level of chips is getting higher and higher, and the requirements for System-on-a-Chip (SoC, System-on-a-Chip) are also getting higher and higher. At present, the mainstream communication SoC chips all include a variety of interconnection protocols between networks (IP, Internet Protocol), and multi-mode and multi-standard SoC communication chips have become the standard configuration of the system. Since multiple systems need to be processed at the same time, and the resources in the chip are limited after all, the preemption and allocation of shared resources becomes particularly critical. Typical examples include: Central Processing Unit (CPU, Central Processing Unit) / (DSP, Digital Signal Processing) processing resource ...

AI Technical Summary

Problems solved by technology

[0003] At present, in the SoC design, the arbitration scheme based on hardware is mainly adopted. This kind of scheme is often arbitrated by the hardware according to the priority of the business. Usually, the design is relatively simple, resulting in poor flexibility.

In addition, when SoC is integrated, it needs to be customized according to the characteristics and requirements of different services. Due to the particularity of ASIC (Application Specific Integrated Circuit), after the design is completed, if the resource allocation rules If it is changed, additional hardware design is required, which will inevitably bring disadvantages to the cost and cycle of chip design
