Arithmetic processing apparatus and control method therefor

A control method for an arithmetic processing apparatus for executing processing using a hierarchical type network in which a plurality of processing nodes are provided in a plurality of layers, the arithmetic processing apparatus including one or more memories for storing a parameter used by each of the plurality of processing nodes for arithmetic processing and a calculation result of the arithmetic processing in each of the plurality of processing nodes, the method comprising:

• setting, in advance of storing the calculation result, a buffer for storing the calculation result in the one or more memories in accordance with a line buffer system for a front group of layers and in accordance with a frame buffer system for a back group of layers in the plurality of layers of the hierarchical type network, where the front group of layers with setting a size of the line buffer based on a circular number of a ring buffer for using the line buffer as the ring buffer, includes a leading layer and can include one or more layers succeeding to the leading layer and the back group of layers follows the front group of layers and includes one or more successive layers in the plurality of layers;
• and
• wherein in setting the buffer, a buffer is allocated for each layer of the front group of layers and a frame buffer is allocated with setting a size of the frame buffer based on a number of lines of one frame for each layer of the back group of layers.

A non-transitory computer-readable recording medium storing a program that causes a computer to perform a control method for an arithmetic processing apparatus for executing processing using a hierarchical type network in which a plurality of processing nodes are provided in a plurality of layers, the arithmetic processing apparatus including one or more memories for storing a parameter used by each of the plurality of processing nodes for arithmetic processing and a calculation result of the arithmetic processing in each of the plurality of processing nodes, the method comprising:

• setting, in advance of storing the calculation result, a buffer for storing the calculation result in the one or more memories in accordance with a line buffer system for a front group of layers and in accordance with a frame buffer system for a back group of layers in the plurality of layers of the hierarchical type network, where the front group of layers with setting a size of the line buffer based on a circular number of a ring buffer for using the line buffer as the ring buffer, includes a leading layer and can include one or more layers succeeding to the leading layer and the back group of layers follows the front group of layers and includes one or more successive layers in the plurality of layers;
• and
• wherein in setting the buffer, a buffer is allocated for each layer of the front group of layers and a frame buffer is allocated with setting a size of the frame buffer based on a number of lines of one frame for each layer of the back group of layers.
