Abstract

The present invention discloses a CPCIE and OpenVPX architecture-based embedded signal processing system. The system comprises a complete machine; the complete machine is provided with nine slots, seven OpenVPX standard load board cards and two CPCIE standard load board cards. With the system adopted, the problem of the incapability of an existing CPCIE architecture embedded system to process big data and high bandwidth and the problem of poor scalability of the existing CPCIE architecture embedded system can be solved; and by means of the advantages of the high speed, high bandwidth and high flexibility of an OpenVPX architecture, data transmission and control of a CPCIE architecture and the OpenVPX architecture are realized through a VPX exchange module, and therefore, the integrated interconnection of the CPCIE architecture and the OpenVPX architecture can be realized, and the advantages of the display control function of the CPCIE architecture and the data processing function of the OpenVPX architecture are realized in an integrated manner.

Description

technical field [0001] The invention belongs to the field of embedded signal processing, in particular to an embedded signal processing system based on CPCIE and OpenVPX architecture. Background technique [0002] In the field of embedded signal processing, especially the military radar signal processing computer, the reinforced computer with CPCIE architecture is widely used as the display control and command platform. The CPCIE bus architecture has the characteristics of high bandwidth and resistance to harsh environments. It has completely replaced the original CPCI bus architecture and has become the mainstream bus technology. However, with the significant increase in data processing capabilities and real-time processing performance requirements of military radar systems, computers with CPCIE architecture can no longer meet the increasing application requirements; in order to adapt to the continuous development of digital technology, the VITA Association proposed the VIT...
