In a neural network, input data and output data are given first, and learning is performed. This learning process (hereinafter referred to as “learning process”
That. ), A value is given to each network 1 connecting the neurons (hereinafter, this is referred to as a “connection value”).

Then, an operation is performed on each of the input values using the corresponding combined value to obtain one output value. That is, the neuron is a multi-input, one-output element. Then, the obtained output value is given to each neuron in the subsequent hierarchy.

FIG. 9 is a block diagram showing a configuration example of this type of neuro operation device. In FIG. 9, the neuro operation device includes a first operation processing unit 1d, a second operation processing unit 2d, a third operation processing unit 3d,
The fourth processing unit 4 d, the processing control unit 2, the broadcast bus 3, the ring bus 4, the storage unit 5 for the processing unit, and the storage unit 6 for the processing unit. Here, four arithmetic processing units are used, but the number of arithmetic processing units is not limited to this, and it is needless to say that the arithmetic processing unit can be configured with another number.

The first to fourth arithmetic processing units 1 d to 4 d are connected to the arithmetic processing control unit 2 by a broadcast bus 3. The arithmetic processing units 1d to 4d are connected by a ring bus 4 so as to make a complete loop.

On the other hand, the storage unit 5 for the arithmetic processing control unit

Next, the operation of the operation process performed in the conventional neuro-operation device having such a configuration will be described with reference to the case of the intermediate layer and the output layer of the above-described neural network as an example.

FIG. 10 is a block diagram showing an example of the configuration of a neuro operation device for performing an operation of the hidden layer. In FIG. 10, five neurons 1b to 5b are allocated to arithmetic processing units 1d to 4d. Here, in the middle layer,
Since the number of the neurons 1b to 5b is one more than that of the arithmetic processing unit, the neuron 5b is assigned to the first arithmetic processing unit 1d in the same manner as the neuron 1b.

As for the operation in the intermediate layer, first, the arithmetic processing control unit 2 outputs the output value of the neuron 1a of the input layer held in the arithmetic processing control unit storage unit 5 to the first through the broadcast bus 3. Arithmetic processing unit 1
to d. A neuron 1b is assigned to the first arithmetic processing unit 1d. Thereby, the first arithmetic processing unit 1d stores the neuron 1a and the neuron 1b in the learning process from the storage unit 6 for the arithmetic processing unit.
Is read out from the network 1 connecting the two, and an operation is performed on the basis of the connection value and the output value of the neuron 1a, and the obtained value is connected to the first arithmetic processing unit 1d. It is stored in the storage unit 6 for the arithmetic processing unit.

Similarly, the arithmetic processing control unit 2 outputs the output value of the neuron 1a in the input layer via the broadcast bus 3 to the second to fourth arithmetic processing units 2d to 2d.
Also give to 4d. Neurons 2b to 4b are assigned to the arithmetic processing units 2d to 4d. As a result, the arithmetic processing units 2d to 4d store the assigned neurons 2b from the arithmetic processing unit storage unit 6.
4b and the connection value given to the network 1 connecting the input layer neuron 1a, read out the connection value, perform an operation based on the connection value and the output value of the neuron 1a, and assign the obtained values to the corresponding values. Arithmetic processing unit 2d ~
It is stored in the processing unit storage unit 6 connected to 4d.

Next, the arithmetic processing control unit 2 calculates the output values of the neurons 2a in the input layer, which are stored in the arithmetic processing control unit storage unit 5, via the broadcast bus 3 for the first to fourth arithmetic operations. This is given to the processing units 1d to 4d. Thereby, each of the processing units 1d to 4d
Reads the connection values given to the network 1 that connects the assigned neurons 1b to 4b and the neuron 2a in the input layer, and reads these connection values and the neuron 2
The calculation is performed based on the output value of “a”, and the obtained value is stored in the processing unit storage unit 6 connected to the corresponding processing units 1d to 4d.

Finally, the arithmetic processing control unit 2 sends the output values of the neurons 3a in the input layer, which are stored in the arithmetic processing control unit storage unit 5, to the first to fourth neurons via the broadcast bus 3. Arithmetic processing units 1d to 4
to d. Thereby, each of the arithmetic processing units 1d to 4d
d reads the connection values given to the network 1 that connects the assigned neurons 1b to 4b and the neuron 3a in the input layer, and performs an operation based on these connection values and the output value of the neuron 3a.

Then, from the values thus obtained,
The arithmetic processing units 1d to 4d calculate the output values of the assigned neurons 1b to 4b. With the above operation, the calculation is performed based on the output value from each neuron of the previous hierarchy and the connection value of the network 1, and the neuron 1b assigned to each of the first to fourth arithmetic processing units 1d to 4d 4b are obtained. Then, the obtained output values are provided to the arithmetic processing control unit 2 via the broadcast bus 3 and stored in the arithmetic processing control unit storage unit 5.

As described above, the operations of the first to fourth arithmetic processing units 1d to 4d are performed simultaneously, that is, in parallel. On the other hand, since the neuron 5b is also assigned to the first arithmetic processing unit 1d, the first arithmetic processing unit 1d operates after the arithmetic operations of the first to fourth arithmetic processing units 1d to 4d are completed. The same operation is performed to determine the output value of the neuron 5b. Then, the obtained output value is provided to the arithmetic processing control unit 2 via the broadcast bus 3 and stored in the arithmetic processing control unit storage unit 5.

Therefore, the operations from the neuron 1b to the neuron 4b in the intermediate layer are performed at the same time, but the calculation of the neuron 5b is performed in the next cycle by time division. FIG.
FIG. 1 is a block diagram illustrating a configuration example of a neuro operation device that performs an operation of an output layer.

In FIG. 11, the neuron 1c in the output layer
Is assigned to the first arithmetic processing unit 1d, and the neuron 2c in the output layer is assigned to the second arithmetic processing unit 2d.

As an operation in the output layer, first, the arithmetic processing control unit 2 outputs the output values of the neurons 1b to 5b of the intermediate layer held in the storage unit 5 for the arithmetic processing control unit via the broadcast bus 3. , To the first arithmetic processing unit 1d and the second arithmetic processing unit 2d.

The first arithmetic processing unit 1d comprises an assigned neuron 1c and an intermediate layer neuron 1b.
An operation is performed based on the connection value provided to the network 1 connecting the communication node 5b and the output values of the neurons 1b to 5b in the intermediate layer to obtain the output value of the neuron 1c.

Similarly, the second arithmetic processing unit 2d
The operation is performed based on the connection value given to the network 1 connecting the assigned neuron 2c and the neurons 1b to 5b in the intermediate layer, and the output value of the neurons 1b to 5b in the intermediate layer. Find the output value.

Then, these determined neurons 1
The output values of c and the neuron 2c are provided to the arithmetic processing control unit 2 via the broadcast bus 3, and are stored in the arithmetic processing control unit storage unit 5.

Although the learning process depends on a learning model, it is necessary to transfer data between arithmetic processing units. In this case, the ring bus 4 is used. by the way,

Alternatively, the second processing unit 2d, which has not been operating normally, is detected by the diagnostic means 7 of the arithmetic processing control unit 2 to operate normally, and then operates.

Then, by the operation of the recovery means 11 of the arithmetic processing control unit 2, the switching means 9 of the switching device 8 returns the connection state from FIG. 7 to the original state as shown in FIG. Next, the effect of the neuro operation device of the present embodiment will be described.

That is, in the present embodiment, the notifying means 10 is further added to the arithmetic processing control unit 2 in the first embodiment. Therefore, in addition to the effects described in the first embodiment, when any of the arithmetic processing units 1d to 4d is diagnosed as not operating normally by the diagnostic means 7 of the arithmetic processing control unit 2, Since the notification information can be obtained by the notification means 10, it is possible to recover the abnormality of the arithmetic processing unit that does not operate normally.

The recovery means 11 is added to the arithmetic processing control unit 2. Therefore, the connection state can be restored by the switching means 9 of the switching device 8, so that the number of arithmetic processing units that can be used for arithmetic processing is prevented from decreasing, and the arithmetic performance before the abnormality is reliably maintained.
