Abstract

PURPOSE:To execute common control, and to shorten operation time, by providing a signal generating means which separately controls plural input/output devices through a common bus from a main processor, and also controls the input/output devices as to each group or in the lump. CONSTITUTION:To a common bus 4 of a CPU1, plural groups, for instance, 2 groups of I/O groups 2, 3 are connected. Each group consists of I/Os 20-2n and 30-3n, respectively, each I/O register an exclusive address and address common to the groups, an exclusive instruction is inputted to the exclusive address from a full line 5, and an instruction common to the groups is transferred to each I/O from a broken line 12 through a common address register 11. In this way, the instructin common to each I/O can be transferred in the lump, and trouble and time required for the operation can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Axis technology division The present invention provides common control (1III) for a plurality of input/output devices under the control of a main processing unit using an S selection signal for each separate outgroup.
This relates to an input/output device control method that is slowed down by III.

(Conventional technique and one point) Conventionally, main processing unit (CPU) If there are multiple input/output *t (Ilo) under OIFMI, each I10 has a -1 control register, and from the CPU Control is performed by sending an individual selection signal to each I10.However, for example, the setting of the 477igJ shield in the display * position for multiple I10s is performed by the CPU even though the same command is used. In order to control, separate selection signals must be given to each individual control unit 14, which is complicated.In this case, it is desirable to use common control.

(3) Purpose of the Invention The present invention @OWA is operated under the control of the main processing area for the input/output device of the input/output unit, and uses a common selection signal outside each separate n11m5.
The purpose is to provide an input/output control method that achieves 1.

(4) I/O configuration In order to achieve the above-mentioned objectives, the input/output car placement control method of the present invention is such that the main processing unit applies individual selection signals to a plurality of input/output devices through a common bus to control each input/output device individually. In the device control method, if multiple input/output devices are divided into multiple groups, the main processing vehicle 1tI/c4! ? The present invention is characterized in that it is provided with a hand IR that generates a selection signal corresponding to a group, and that the input/output devices of the group O are commonly controlled.

(5) Issu @O implementation example The figure is a configuration explanatory diagram of an embodiment of the present invention.

In Figure 1111, 41 ridgesffl9 connected to CPU 1O common path 4, for example 2!1 LOI 10 group 2,
Think about 5. Each group is l102s~2. And 170 of each panl from 11051 to 3m has a separate OI! It has a register for IIIll, and the nine instructions with the address of CPU1 are indicated by solid lines.
It is sent to IX Todoroki 110 via 5t and processed by Taibetsu. The above is based on the conventional 0111111IB1 method, but in the present invention, the upper digits of each l10C) address are specified as a common address, the lower digits are all @0'', and a group is selected. In other words, when the CPU is set up, an instruction with a fixed group address of fi is sent to Ilo of the prestige group via the common address register 11 indicated by a broken line. The group mother O common control is carried out. In the embodiment, both 1 and 2 are distinguished by 夿 and 翿■, and this can be treated as a common line by the control within I10. .

When all I10s are to be commonly controlled at once, it is sufficient to send all the common codes indicating that the control is common.

(6) Effects of the Invention As explained above, according to the present invention, by providing a common signal to the CPU group @0, it is possible to achieve a common signal between the CPUs and the group @0. 1111
This is the third time to perform the hook. In this way, in the case of the same command such as initialization, by performing -fimu- instead of controlling each command separately, the program can be simplified and processed faster. Furthermore, each Ilo is set up without any time difference, which apparently reduces the setup time.

Claims (1)

[Claims] In the input/output device control method in which individual selection signals are given to multiple input/output devices through a common bus to control each device separately, the input/output l1I7&rIt of I[a are divided into single and double-chain O groups. This is an input/output device control method in which the main processing unit is equipped with a means for generating a selection signal corresponding to the valley group, and the input/output devices of the Weiyu group are used as a common WIJf/R.
