ABSTRACT:
An information processing apparatus includes a communication processing unit configured to communicate with an external communication device; and a data processing unit configured to communicate with the communication processing unit and carry out data processing. The communication processing unit includes a memory where data transmitted and received between a communication device and the data processing unit is temporarily stored, and a control unit configured to control data writing and data reading. When a command packet received from the communication device is a data reading request, the control unit acquires data from the memory and transmits the data to the communication device. When the command packet received from the communication device is a data writing request, the control unit stores data in the memory, acquires data from the memory in response to the request from the data processing unit, and outputs the data to the data processing unit.
