Abstract :
Aiming at the problem of data transfer for virtual-machine monitor in device access, a communications mode in double systems based on multi-core processor is proposed. Two key problem in this mode buffer overflow and package pseudo loss are analyzed, communications mechanism based on Inter-processor interrupts and shared memory is constructed, data transfer between virtual-machine monitor and IO process machine is implemented. Efficiency of communications is enhanced by IPI multiplex, cache customization ect. Finally, guide line of communications such as arrival ratio, transfer ratio of package, system load is tested and conclusion is presented. Experimental results showed that the communications mode in double systems based on multi-core processor could provide communications platform with stabilization and high efficiency.
