Abstract

PURPOSE:To improve the processing capacity by dividing into two tasks of a peripheral equipment control means of a floating task which can be operated by an arbitrary central processing unit, and an interruption control means of a fixed task which can be operated only by a fixed central processing unit in order to receive a completion interruption, and providing a part of the floating task which can be operated by an arbitrary central processing unit. CONSTITUTION:A peripheral equipment control means 12 of a central processing unit 20 is generated as a floating task which can be operated by an arbitrary central processing unit 20, and an interruption control means 16 is generated as a fixed task which can be operated only by a fixed central processing unit 20. In such a way, the time when the task is operated by the fixed central processing unit becomes extremely small, and in the case when plural central processing units exist, the peripheral equipment control system is dispersed to each central processing unit, a remarkable improvement of the processing capacity as a whole can be contrived.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a peripheral device control method for an electronic computer system having a plurality of central processing units, and in particular to speeding up peripheral device control means.

Prior Art Conventionally, peripheral device control means are generated in one task,
In addition, in order for the peripheral device to notify the central processing unit of the completion interrupt after the processing is completed, it is necessary to determine in advance the number of the central processing unit to which the peripheral device will notify the completion interrupt when the processing is completed. Since the completion interrupt from the peripheral device is notified only to the fixed central processing unit of the peripheral device, the peripheral device control means is generated by one fixed task that can only be operated by the fixed central processing unit.

Problems to be Solved by the Invention Since the conventional peripheral device control means described above is generated by one fixed task, even if there are multiple central processing units, the peripheral device control means is generated by one fixed central processing unit. Since it is designed to only work on the computer, it is processed by a fixed central processing unit.

When there are multiple peripheral device control means, and when one peripheral control means has multiple requests for that peripheral device control means, when one peripheral device control means is executed, the central processing unit controls the peripheral device. Since the central processing unit is occupied by the central processing unit, other peripheral device controlling units and other requests to the peripheral device controlling unit cannot operate even though there are other free central processing units, so the overall processing speed is slow. It has the disadvantage of becoming.

This problem becomes worse as the number of peripheral device control means increases.
Even if there is only one peripheral device control means, this problem becomes more noticeable as the demands on the peripheral device control means increase.

The present invention has been made in view of the above-mentioned conventional situation,
