Description

technical field

[0001] The invention belongs to the field of satellite communication, in particular to a VPX-based satellite communication data processing module. Background technique

[0002] The traditional satellite communication data processing module is realized by parallel bus architecture, which has low integration, large space occupation and insufficient interface expansion capability. With the continuous development of current integrated circuit, processor technology, and programmable logic technology, the traditional parallel bus can no longer meet the communication requirements of large bandwidth and high speed in the field of satellite communication.

[0003] VPX is a next-generation advanced computing platform standard formulated by VITA to meet the requirements of high reliability and high bandwidth in harsh environments. Applying VPX to the satellite communication data processing module can greatly improve the efficiency of satellite communication. Contents...
