CPU console redirecting method and system and CPUs

The embodiment of the invention discloses CPU console redirecting method and system and CPUs. The system comprises a plurality of CPUs connected through buses, and the plurality of CPUs include at least one first CPU and at least one second CPU. The method comprises the following steps of: distributing buffer areas to the second CPUs on the internal memories of the first CPUs; constructing virtual bus equipment respectively on the first CPUs and the second CPUs and associating the first CPUs and the second CPUs through the virtual bus equipment; and carrying out reading and writing operations on CPU information through the buffer areas by the first CPUs and the second CPUs. In the embodiment of the invention, the information of the second CPUs is read and written on the first CPUs, and the reading and writing operations are carried out without a serial port; and moreover, in the redirecting process of a CPU console, a network is not depended, and the first CPUs can view all run progresses of the second CPUs and the print information of a kernel, thereby the convenience and the flexibility for reading the CPU information are enhanced.
