A multiprocessor system includes first and second processors independently executing application functions associated with one or more applications using an open operating system (OS), a multiport memory, a first nonvolatile memory coupled to the first processor via a first bus, and a second nonvolatile memory coupled to the second processor via a second bus. The multiport memory includes a memory cell array divided into a plurality of memory banks including a shared memory bank commonly accessed by the first and second processors via respective first and second ports, and an internal register disposed outside the memory cell array and configured to control access authority to the shared memory bank by the first and second processors, wherein different application functions are independently executed in parallel by the first and second processors using the multiport memory as a data transfer mechanism.
