Abstract
The present invention provides an information processing apparatus capable of mounting an optional hardware. The information processing apparatus comprises a processor, an image processing circuit and a socket to which the optional hardware is to be mounted, wherein the optional hardware being connected to the socket communicates with the image processing circuit. The processor transmits a predetermined packet to the optional hardware mounted to the socket, receive a response packet to the predetermined packet from the image processing circuit, determines whether or not the received response packet is an expected response packet, and controls supplying power to the optional hardware in accordance with a determination result of the received response packet.
Claims19
An information processing apparatus capable of mounting an optional hardware, the information processing apparatus comprising:
- an image processing circuit;
- a socket to which the optional hardware is to be mounted, wherein the optional hardware being connected to the socket communicates with the image processing circuit;
- a memory that stores instructions;
- and
- a processor that executes the instructions stored in the memory to:
- transmit a predetermined packet to the optional hardware mounted to the socket;
- receive a response packet to the predetermined packet from the image processing circuit;
- determine whether or not the received response packet is an expected response packet;
- and
- control supplying power to the optional hardware in accordance with a determination result of the received response packet.
A method of controlling an information processing apparatus including an image processing circuit and a socket capable of mounting an optional hardware, wherein the optional hardware being connected to the socket communicates with the image processing circuit, the method comprising:
- transmitting a predetermined packet to the optional hardware connected to the socket;
- receiving a response packet to the predetermined packet from the image processing circuit;
- determining whether or not the response packet is an expected response packet;
- and
- controlling supplying power to the optional hardware in accordance with a determination result.
An information processing apparatus, comprising:
- an image processing circuit;
- a socket that is capable of connecting an optional hardware, wherein the optional hardware being connected to the socket communicates with the image processing circuit;
- and
- a processor,
- wherein the processor transmits a predetermined packet to the optional hardware being connected to the socket,
- upon receiving a response packet produced by the optional hardware and the image processing circuit by processing the predetermined packet, the processor determines whether or not the response packet is an expected response packet, and
