Title:

OPERATION UNIT, METHOD AND DEVICE CAPABLE OF SUPPORTING OPERATION DATA OF DIFFERENT BIT WIDTHS

Document Type and Number:

WIPO Patent Application WO/2018/024093

Kind Code:

A1

Abstract:

An operation unit, operation method and operation device for configuring a bit width of operation data involved in an operation by configuring a bit-width domain in a configuration instruction. The method comprises: upon executing an operation according to an instruction, firstly determining if an operator having a bit width identical to that of operation data indicated by an operand in the instruction is present; if yes, sending the operand directly to a corresponding operator; otherwise, generating an operator merging policy and merging multiple operators into a new operator according to the operator merging policy, such that a bit width of the new operator matches the bit width of the operand, and then sending the operand to the new operator; and enabling the operator acquiring the operand to execute a neural network operation/matrix operation/vector operation. The operation unit, operation method and operation device can support operations on operation data having different bit widths, thus realizing highly effective neural network operations, matrix operations and vector operations, while also reducing the quantity of operators and reducing hardware area at the same time.
