Claim 19:
20. A method for performing neural network operations using an integrated circuit chip apparatus comprising a main processing circuit, and a plurality of basic processing circuits comprising data type conversion circuits configured to convert data between a floating data type and a fixed point data type, the method comprising:
transferring data and a computation instruction from the main processing circuit to the plurality of basic processing circuits;
when the data transferred to the basic processing circuits is in the floating point data type, converting, by the plurality of basic processing circuits, the data into the fixed point data type;
performing, by the plurality of basic processing circuits, a first set of neural network computations in parallel in the fixed point data type on the data to obtain computation results in the fixed point data type;
convert the computation results in the fixed point data type into the floating point data type;
transferring the computation results to the main processing circuit in the floating point data type; and
performing, by the main processing circuit, a second set of neural network computations in series on the computation results.
