Abstract
An electronic apparatus includes a circuit board including a processor, and a pluggable board detachably coupled to the circuit board, wherein the pluggable board includes a first arbitration circuit that autonomously outputs a control request to the circuit board, and the circuit board performs processing based on the control request and supplies a result of the processing to the pluggable board.
Claims15
An electronic apparatus comprising:
- a circuit board including a processor;
- and
- a pluggable board detachably coupled to the circuit board, wherein
- the pluggable board includes a first arbitration circuit that autonomously outputs a control request to the circuit board, and
- the circuit board performs processing based on the control request and supplies a result of the processing to the pluggable board.
A pluggable device detachably used in an electronic apparatus, the pluggable device comprising:
- a communication interface that performs transmission and reception of control data between the communication interface and a circuit board of the electronic apparatus;
- and
- a first arbitration circuit that autonomously outputs a control request to the circuit board and processes information received from the circuit board, wherein
- the first arbitration circuit that controls or arbitrates output timing of the control request to the circuit board.
A communication control method in an electronic apparatus including a pluggable device, the communication control method comprising:
- detachably connecting the pluggable device to an circuit board of the electronic apparatus;
- outputting a control request from the pluggable device to the circuit board;
- and
- performing, in the circuit board, processing based on the control request and supplying a result of the processing to the pluggable device.
