Arbitration control method, communication method, arbitrator and communication system

Abstract

The invention relates to an arbitration control method, a communication method using the arbitration control method, an arbitrator and a communication system using the arbitrator. The arbitration control method comprises the following steps of: sequencing communication requests, wherein the sequencing is related to the link distance and submission time of the communication requests; screening thesequenced communication requests and submitting the screened communication requests; arbitrating the communication requests according to the types of the submitted communication requests and returning an arbitration failure response or arbitration success response; and updating a link record and a credit record according to the arbitration response. By the centralized management and allocation ofcredit and links of communication resources, the arbitration process is simplified, the streamline arbitration capability is improved and the communication efficiency of the links is increased.

Description

technical field [0001] The invention relates to an arbitration control method, a communication method, an arbiter and a communication system. Background technique [0002] With the development of integrated circuit technology and system-on-chip (SoC, System-on-Chip), the density of integrated circuits on chip is getting larger and larger, which can accommodate more functional units, such as integrating more processor cores (core), Memory control for communication between processor core and main memory, interface unit for communication between chip and other external devices, and more third-party IP cores, etc. The increase of on-chip functional units puts forward higher requirements for on-chip communication bandwidth and delay. At the same time, the reduction of integrated circuit feature size makes the delay caused by wiring account for an increasing proportion of on-chip communication. These The emergence of problems makes the traditional bus interconnection no longer su...
