Embodiment Construction

[0055] The present invention will be further described below in conjunction with accompanying drawing:

[0056] figure 1 It is a dynamic partially reconfigurable software radio system architecture block diagram aimed at by the present invention. Such as figure 1 As shown, the system consists of three parts: waveform application, SCA software architecture, and DPR FPGA. The waveform application in the example figure is composed of four components, the FPGA is divided into three dynamic partial reconfigurable areas, and the core framework in the SCA completes the component management and resource allocation of the entire system. The resource virtualization technology and the waveform deployment mechanism proposed by the present invention are to establish the mapping relationship between the waveform application components and the reconfigurable area of ​​the FPGA dynamic part.

[0057] figure 2 It is a schematic diagram of the reconfigurable function of the dynamic part. S...

Abstract

The invention relates to an SCA-based dynamic partially reconfigurable device resource virtualization and waveform deployment method, and solves the problems that the existing SCA specification and related implementation only provide support for FPGA global dynamic reconstruction, a DPR technology is not supported, the reconstruction granularity is too large, resources cannot be effectively subjected to space-time multiplexing, and the like. According to the method, a mapping relationship from a waveform component to an FPGA dynamic part reconfigurable region is established. By designing and configuring the domain description file under the core framework, the overall architecture of a software system is not changed while the system function is expanded under the specification of SCA, thetransportability of components and the isomerism of a platform are ensured, and the development and maintenance complexity is reduced.

Description

technical field [0001] The invention relates to a hardware device virtualization and software deployment mechanism in a software radio system. Specifically, it involves hardware resource virtualization of dynamically partially reconfigurable programmable logic gate array devices and dynamic partially reconfigurable deployment of waveform applications in software radio systems based on Software Communications Architecture (SCA), This method uses eXtensible Markup Language (eXtensible Markup Language, XML) for scheme design, which has greater flexibility and improves the hardware resource utilization rate and waveform deployment efficiency of the software defined radio system. Background technique [0002] There are a wide variety of communication systems in the field of civil wireless communication, among which short-distance wireless communication mainly includes WIFI, Bluetooth, Zigbee, REID, etc., and long-distance wireless communication includes communication systems such...
