In one possible implementation, as shown in fig. 2c, the operation module 12 may further include one or more branch operation sub-modules 123, and the branch operation sub-module 123 is configured to forward data and/or operation instructions between the master operation sub-module 121 and the slave operation sub-module 122. The main operation sub-module 121 is connected to one or more branch operation sub-modules 123. Therefore, the main operation sub-module, the branch operation sub-module and the slave operation sub-module in the operation module are connected by adopting an H-shaped structure, and data and/or operation instructions are forwarded by the branch operation sub-module, so that the resource occupation of the main operation sub-module is saved, and the instruction processing speed is further improved.

Fig. 2d shows a block diagram of a linear rectification function enable instruction processing apparatus according to an embodiment of the present disclosure. In one possible implementation, as shown in FIG. 2d, a plurality of slave operation sub-modules 122 are distributed in an array.

Each slave operation submodule 122 is connected to another adjacent slave operation submodule 122, the master operation submodule 121 is connected to k slave operation submodules 122 of the plurality of slave operation submodules 122, and the k slave operation submodules 122 are: n slave operator sub-modules 122 of row 1, n slave operator sub-modules 122 of row m, and m slave operator sub-modules 122 of column 1.

The k slave operation submodules are used for forwarding data and instructions between the master operation submodules and the plurality of slave operation submodules. Therefore, the plurality of slave operation sub-modules are distributed in an array, the speed of sending data and/or operation instructions to the slave operation sub-modules by the master operation sub-module can be increased, and the instruction processing speed is further increased.

Fig. 2e shows a block diagram of a linear rectification function enable instruction processing apparatus according to an embodiment of the present disclosure.

The root port 401 is connected to the master operation submodule 121, and the plurality of branch ports 402 are connected to the plurality of slave operation submodules 122, respectively. The tree sub-module 124 has a transceiving function, and is configured to forward data and/or operation instructions between the master operation sub-module 121 and the slave operation sub-module 122. Therefore, the operation modules are connected in a tree-shaped structure under the action of the tree-shaped sub-modules, and the speed of sending data and/or operation instructions from the main operation sub-module to the auxiliary operation sub-module can be increased by utilizing the forwarding function of the tree-shaped sub-modules, so that the instruction processing speed is increased.

In one possible implementation, the tree submodule 124 may be an optional result of the apparatus, which may include at least one level of nodes. The nodes are line structures with forwarding functions, and the nodes do not have operation functions. The lowest level node is connected to the slave operation sub-module to forward data and/or operation instructions between the master operation sub-module 121 and the slave operation sub-module 122.

In one possible implementation, the tree submodule 124 may include a plurality of nodes of an n-ary tree structure, and the plurality of nodes of the n-ary tree structure may have a plurality of layers.

For example, fig. 2f shows a block diagram of a linear rectification function enable instruction processing device according to an embodiment of the present disclosure. As shown in FIG. 2f, the n-ary tree structure may be a binary tree structure with tree-type sub-modules including 2 levels of nodes 01. The lowest level node 01 is connected with the slave operation sub-module 122 to forward data and/or operation instructions between the master operation sub-module 121 and the slave operation sub-module 122.

In this implementation, the n-ary tree structure may also be a ternary tree structure or the like, where n is a positive integer greater than or equal to 2.

In one possible implementation, the operation domain may also include a read-in amount or a memory address of the read-in amount. The control module 11 is further configured to obtain a read amount, and obtain a plurality of data to be calculated according to the read amount. The data volume of the plurality of data to be operated can be smaller than or equal to the read-in volume.

In this implementation, the read-in amount may be a data amount of the acquired plurality of data to be operated on, and may be a size of the acquired data to be operated on. When the operation field directly contains a specific numerical value of the read amount, the numerical value may be determined as the read amount. When the memory address of the read amount is included in the operation field, the read amount can be acquired from the memory address.

In one possible implementation manner, when the read-in amount is not included in the operation domain, the plurality of data to be operated may be acquired according to a preset default read-in amount. The acquired data amount of the plurality of data to be operated can be smaller than or equal to the default read-in amount.

By the mode, the data size and the size of the data to be operated can be limited, the accuracy of the operation result is ensured, and the device can execute the linear rectification function activating instruction.

The queue storage submodule 113 is configured to store an instruction queue, where the instruction queue includes multiple instructions to be executed that are sequentially arranged according to an execution order, and the multiple instructions to be executed include the linear rectification function activation instruction.

In this implementation manner, the execution order of the multiple instructions to be executed may be arranged according to the receiving time, the priority level, and the like of the instructions to be executed to obtain an instruction queue, so that the multiple instructions to be executed are sequentially executed according to the instruction queue.

In one possible implementation, as shown in fig. 2 a-2 f, the control module 11 may further include a dependency processing sub-module 114.

The dependency relationship processing submodule 117 is configured to, when it is determined that a first to-be-executed instruction in the plurality of to-be-executed instructions is associated with a zeroth to-be-executed instruction before the first to-be-executed instruction, cache the first to-be-executed instruction in the instruction storage submodule 114, and after the zeroth to-be-executed instruction is executed, extract the first to-be-executed instruction from the instruction storage submodule 114 and send the first to-be-executed instruction to the operation module 12.

The method for determining the zero-th instruction to be executed before the first instruction to be executed has an incidence relation with the first instruction to be executed comprises the following steps: the first storage address interval for storing the data required by the first to-be-executed instruction and the zeroth storage address interval for storing the data required by the zeroth to-be-executed instruction have an overlapped area. On the contrary, there is no association relationship between the first to-be-executed instruction and the zeroth to-be-executed instruction before the first to-be-executed instruction, which may be that there is no overlapping area between the first storage address interval and the zeroth storage address interval.

By the method, according to the dependency relationship between the first to-be-executed instruction and the zeroth to-be-executed instruction before the first to-be-executed instruction, the subsequent first to-be-executed instruction is executed after the execution of the previous zeroth to-be-executed instruction is finished, and the accuracy of the operation result is ensured
