Intel’s Quick Path Interconnect technology is abbreviated as QPI, which is translated as Quick Path Interconnect. It is used to achieve direct interconnection between chips. Which of the following statements about QPI is correct?
A . Another highlight of QPI is that it supports multiple system bus connections, which Intel calls multi-FSB.
B . A set of QPI has 10 data transmission lines, as well as clock signals for the transmitter (TX) and receiver (RO)
C . Total QPI bus bandwidth = number of transmissions per second (i.e QPI frequency) x valid data transmitted each time (i.e 16bit/8=2Byte) x bidirectional
D . QPI is a serial high-speed point-to-point connection protocol based on packet transmission, which uses differential signals and specialized clocks for transmission.
