Data transmission method and calculation apparatus for neural network, electronic apparatus, computer-readable storage medium and computer program product

A calculation apparatus, comprising:

• a memory, a first direct memory, a write memory, a second direct memory, a calculation circuit, and a control circuit;
• wherein,
• the first direct memory is configured to write weights stored in the memory to the write memory;
• the control circuit is configured to acquire a weight specification of weight data stored in the memory, compare the weight specification with a specification of the write memory in terms of size, to obtain a comparison result, divide the write memory into a first-in first-out write memory and a multiplexing write memory, according to the comparison result, and determine data reading policies of the first-in first-out write memory and the multiplexing write memory, according to the comparison result;
• the second direct memory is configured to read weights from the first-in first-out write memory and the multiplexing write memory, according to the data reading policies, and load the weights to the calculation circuit.
