ABSTRACT:
A data transfer system includes first and second microprocessors, each having a data input portion, a data output portion, and a data transfer control signal input/output portion to input or output a data transfer request signal for requesting permission for transfer of data or a data transfer permission signal representing the permission for transfer of data. A first data transfer path connects the data output portion of the first microprocessor with the data input portion of the second microprocessor. A second data transfer path connects the data output portion of the second microprocessor with the data input portion of the first microprocessor. A data transfer control signal transmitting path connects the data transfer control signal input/output portion of the first microprocessor with the data transfer control signal input/output portion of the second microprocessor to feed the data transfer request signal or the data transfer permission signal between the microprocessors.
