CPU interconnect device
Abstract:
The present disclosure provides a CPU interconnect device, the CPU interconnect device connects with a first CPU, which includes a quick path interconnect QPI interface and a serial deserial SerDes interface, the quick path interconnect QPI interface receives serial QPI data sent from a CPU, converts the received serial QPI data into a parallel QPI data, and outputs the parallel QPI data to the serial deserial SerDes interface; the serial deserial SerDes interface converts the parallel QPI data output by the QPI interface into a high-speed serial SerDes data and then send the high-speed serial SerDes data to another CPU interconnect device connected with another CPU. The defects of poor scalability, long data transmission delay, and a high cost of an existing interconnect system among CPUs can be solved.
