The address control unit is a register that determines how many microinstructions one microphone colloquial word read into the microphone colloquial language reading register is handled as. The address register is a register that holds the address of the currently executed instruction and υ incremented by 1 (3). The address selector is a selector for selecting either the output of the microphone colloquial reading register or the output of the address register. The microinstruction decode control unit is a control unit that decodes the output of the microphone spoken word read register.

With the above configuration, the microphone spoken word includes an instruction for instructing whether one microphone spoken word is treated as one micro-instruction or multiple micro-instructions, and one microphone spoken word is treated as one micro-instruction or multiple micro-instructions. When instructed to be treated as an instruction, a plurality of microinstructions are executed in a predetermined order. Further, in the above configuration, when the execution of the microinstruction is completed, the next microphone spoken word is read out in preparation for the next process.

(Explanation of Examples) Next, the present invention will be explained in detail with reference to the drawings.

FIG. 2 shows an embodiment of the invention.

In FIG. 2, the microprogram control device according to the present invention includes a microword storage device 1, a microphone spoken word reading register 2, an address selector 4, an address register 5, an address control section 6, and a microinstruction decoding control section 7. It is established from .

First, the operation when there is an instruction of w11 micro=1 microinstruction 1 in the address control area will be explained in detail.

First, when the microphone colloquial language is read out to the microphone colloquial language reading register 2, the address control unit 6 reads 11 microwords=
1 determines that the instruction for microinstruction 1 has been issued,
If the microphone spoken word is a branch instruction, the address selector 4 selects the signal sent from the microphone spoken word reading register 2 to the output signal line 101.

The output of the address selector 4 is sent out from the address selector 4 via the output signal line 107 as the address of the next microphone spoken word.

The next microphone spoken word is read into the microphone spoken word reading register 2 according to this address.

If this microphone command is not a branch instruction, the address incremented by +1 from the output of the address selector 4 is sequentially sent to the address register 5 for each effective sunset check, and this action is controlled by the address register 5. The output signal line 106 is selected by the address selector 4 and executed.

Therefore, the microphone spoken words stored in the location designated by the address register 5 are sequentially read out as the address of the next microphone spoken word.

In addition, the output signal line 1 from the microphone colloquial reading register 2
The microinstruction sent through the microinstruction controller 03 is decoded by the microinstruction decode control section 7, and the microprogram control device controls various operations in accordance with the decoded signal.

Next, the operation when there is an instruction of 11 microwords=2 microinstructions 1 in the address control area will be described in detail.
When the microphone colloquial language is read into the microphone colloquial language reading register 2, the address control unit 6 determines that the instruction 11 microwords=2 microphone day command 1 has been issued.

This state is notified to the microinstruction decode control section 7 via the signal line 108.

The microinstruction decoding control unit 7 decodes the good signal sent from the microphone colloquial reading register 2 via the output signal line 101 as the first microinstruction, and the microprogram control device performs various operations according to the decoded signal. Control.

At the same time, the microinstruction decode control section 7 sends out an instruction signal via the signal line 104 so as to hold the contents of the one-microword read register 2 and the address register 5, respectively.

Thereafter, when the processing of the first microinstruction is completed, the signal sent from the microphone colloquial reading register 2 via the output signal line 103 is decoded as the next microinstruction.

According to the decoded signals, the microprogram controller controls various operations.

When this process is completed, the instruction to hold the contents of the microphone colloquial reading register 2 and the address register 5 is stopped, and the signal sent from the address register 5 via the output signal line 106 is used as the next microword address.
