Signal processing platform network architecture and hardware equipment virtualization method and system

Abstract

The invention belongs to the technical field of platform resource virtualization, and particularly relates to a signal processing platform network architecture and hardware equipment virtualization method and system, which adopt a hierarchical network structure combining from top to bottom and from bottom to top, and the hierarchical network structure comprises a system domain formed by interconnecting a plurality of domains through a network, wherein each domain is formed by platforms defined by different bus standards through a network communication protocol, each platform is provided with aplurality of board cards, and a plurality of heterogeneous signal processors are embedded in the corresponding board cards; and the system domain connects domain servers of different domains to perform inter-domain service data interaction according to different application task requirements, the system domain server manages resources of the multiple domains, and the domains are mutually independent. According to the invention, signal processing hardware equipment is subjected to unified specification virtualization description, the management efficiency and the intercommunication and interconnection effects of the hardware equipment are improved, plug and play and random expansion of each hardware equipment in a network are facilitated, each communication demand can be better adapted, and the system performance is improved.

Description

technical field [0001] The invention belongs to the technical field of platform resource virtualization, and in particular relates to a network architecture of a signal processing platform and a method and system for virtualizing hardware devices of a hierarchical heterogeneous signal processing platform. Background technique [0002] With the concept of Software Defined Radio (SDR) and Software Communication Architecture (SCA), the number of hardware devices in modern signal processing platforms is increasing explosively and the models are not oriented. The traditional hardware device virtualization description method is either aimed at a single type of hardware device in a simple network, or has poor interoperability and compatibility, cannot fully utilize the computing power of different hardware devices, and it is difficult to achieve "plug and play" of different hardware devices. Use" and the free expansion of the hardware system. For example, the objects in Alibaba Cl...

Problems solved by technology

Although the above technologies can satisfy the virtualization description of a single device or some devices of a specific model, different high-performance processors (FPGA, DSP, GPU, etc.), different types and manufacturers of boards, and different buses included in modern signal processing platforms Interface hardware platforms (ATCA, VPX, CPCI platforms) and other hardware devices also need to be described in a unified and standardized way to meet actual application requirements
