Method and apparatus for generating address of data of artificial neural network

An apparatus for generating an address of data for an artificial neural network,

• a processor, a memory, and an interface, wherein the processor executes a program stored in the memory to perform:
• performing an N-dimensional loop operation based on a predetermined parameter to generate the address of the data;
• and
• generating the address of the data in order according to a predetermined direction,
• wherein the predetermined parameter includes an address value of first data in a memory of the artificial neural network, a repetition number of each loop of the N-dimensional loop operation, and an address offset of each loop of the N-dimensional loop operation.

An accelerator of an artificial neural network,

• an address generating processor, a computation processor, and a memory, wherein the address generating processor executes a program stored in the memory,
• performing an N-dimensional loop operation based on a predetermined parameter to generate the address of data to be processed by the accelerator;
• and
• generating the address of the data in order according to a predetermined direction,
• wherein the predetermined parameter includes an address value of first data in the memory, a repetition number of each loop of the N-dimensional loop operation, and an address offset of each loop of the N-dimensional loop operation, and is pre-determined based on at least one of a size of kernel data stored in the memory, a size of feature map data stored in the memory, a size of pooling operation, and stride value.
