Information processor, method for controlling information processor, and non-transitory computer-readable storage medium for storing control program for information processor

A control method for an information processing apparatus including a control device, an interface device, and an arithmetic processing device, wherein

• the control device is configured to:
• cause the arithmetic processing device to individually execute a plurality of divided first control commands as one processing unit in a predetermined execution order, via the interface device;
• detect an interrupt issued from the arithmetic processing device or the interface device;
• generate a second control command for identifying an interrupt factor of the detected interrupt;
• preferentially arrange the generated second control command over the unexecuted first control commands to change the execution order;
• and
• execute the first control commands and the second control command in the changed execution order.

A non-transitory computer-readable storage medium for storing a control program which causes an information processor to perform processing, the information processor including a control device, an interface device, and an arithmetic processing device, the processing comprising:

• causing the arithmetic processing device to individually execute a plurality of divided first control commands as one processing unit in a predetermined execution order, via the interface device;
• detecting an interrupt issued from the arithmetic processing device or the interface device;
• generating a second control command for identifying an interrupt factor of the detected interrupt;
• preferentially arranging the generated second control command over the unexecuted first control commands to change the execution order;
• and
• executing the first control commands and the second control command in the changed execution order.
