The embedded integration of aviation electronic equipment has developed from single-core and dual-core to multi-core,integrating the performance and processing power that can only realized by multiple single-core processors into a symmetrical multi-processing architecture,which improves the system integration and reduces the volume and power consumption of the equipment.In the paper,based on PowerPC high-performance multi-core processing platform is designed which can realize multi-core parallel processing and provide a variety of congfigurable high-speed interfaces.The practical verification and engineering application show that this platform can meet a variety of high-performance aviation airborne products.
