Multi processor system having direct access booting operation and direct access booting method therefore

摘要

A multiprocessor system having a direct access boot operation and a direct access boot method are provided to substantially reduce a boot error of processor that does not provide a memory link architecture in the multiprocessor system. In an embodiment of the invention, a multiprocessor system includes: a first processor configured to perform a first predetermined task; a second processor configured to perform a second predetermined task; a multiport semiconductor memory device coupled to the first processor and the second processor, the multiport semiconductor memory device including at least one shared memory area, the multiport semiconductor memory device configured to provide access to the at least one shared memory area by the first processor and the second processor; and a non-volatile memory device coupled to the first processor and the second processor, the non-volatile memory device storing a first boot code associated with the first processor and a second boot code associated with the second processor, the multiprocessor system configured to provide the first processor direct access to the non-volatile memory area during a boot operation and indirect access to the non-volatile memory area otherwise.
