Integrated microprocessor with internal bus and on-chip peripheral

摘要

A microprocessor assembly includes an integrated microprocessor and an external bus having a plurality of signal lines and a corresponding number of terminals connected to the integrated microprocessor. The integrated microprocessor includes a plurality of terminals; a core processor; at least one quasi-external bus having a plurality of signal lines; a bus control unit connecting the core processor to the quasi-external bus; a device connecting the quasi-external bus to the external bus through a corresponding number of terminals; and at least one peripheral connected to the quasi-external bus. The quasi-external bus has at least the same number of signal lines carrying the same signal as the external bus, and the quasi-external bus has the same control performance as the external bus, for connecting a peripheral without modification to both the external bus and the quasi-external bus.
