Abstract
In order to incorporate a new device in an information processing apparatus, a) dividing a control system of the information processing apparatus into a plurality of control system; one control system of the plurality of control systems carrying out processing for controlling the new device by directly accessing the same; c) another control system of the plurality of control system controlling the one control system directly accessing the new device and carrying out processing for controlling the same, are carried out.
Claims16
A method of incorporating a new device in an information processing apparatus, comprising:
- dividing a control system of the information processing apparatus into a plurality of control systems that are independent from each other, each of which plurality of control systems is controlled by a different computer program;
- causing a first CPU which is designated for a first control system of the plurality of control systems to carry out processing for controlling the new device by directly accessing the new device;
- and
- causing a second CPU which is designated for a second control system of the plurality of control systems, and is different from the first CPU, to control the first CPU which directly accesses the new device to carry out processing for controlling the new device.
An information processing apparatus comprising:
- a first processing part;
- a second processing part;
- a first control part configured to control at least one of the first processing part and the second processing part;
- a second control part configured to control at least one of the first processing part and the second processing part;
- and
- a switching part configured to switch control of the first processing part to be under the control of the first control part and to switch control of the second processing part to be under the control of the second control part, for adding hardware to the information processing apparatus, wherein:
- the first processing part and the second processing part are separate CPUs, respectively;
- the first processing part, control of which is switched by the switching part to be under the control of the first control part, accesses the hardware and carries out processing for controlling the hardware;
- and
- the second processing part, control of which is switched by the switching part to be under the control of the second control part, controls the first processing part which directly accesses the hardware and carries out the processing for controlling the hardware.
A computer readable information recording medium storing a program which, when executed by a computer processor, carries out:
- incorporating a new device in an information processing apparatus;
- dividing a control system of the information processing apparatus into a plurality of control systems that are independent from each other, each of which plurality of control systems is controlled by a different computer program;
- causing a first CPU which is designated for a first control system of the plurality of control systems to carry out processing for controlling the new device by directly accessing the new device;
- and
- causing a second CPU which is designated for a second control system of the plurality of control systems, and is different from the first CPU, to control the first CPU which directly accesses the new device and carries out processing for controlling the new device.
