Embodiments of the present disclosure provide a data processing method implemented at an edge switch, an electronic device, and a program product. For example, a data processing method implemented at an edge switch is provided. The method includes receiving at least two data packets for floating-point arithmetic operations from at least one source device. In addition, the method may include acquiring corresponding floating-point numerical sequences respectively from the at least two data packets; and acquiring a floating-point arithmetic method from at least one data packet of the at least two data packets to determine a floating-point arithmetic result of the corresponding floating-point numerical sequences. The method may further include sending the floating-point arithmetic result to a target device indicated by the at least one data packet of the at least two data packets.

An apparatus comprises combined divide/square root processing circuitry to perform, in response to a divide instruction, a given radix-64 iteration of a radix-64 divide operation, and in response to a square root instruction, a given radix-64 iteration of a radix-64 square root operation; in which: the combined divide/square root processing circuitry comprises shared circuitry to generate at least one output value for the given radix-64 iteration on a same data path used for both the radix-64 divide operation and the radix-64 square root operation.

An instruction to perform a shift and divide operation is executed. The executing includes shifting a value in a specified direction by a selected amount to provide a dividend, the selected amount being user-defined. The dividend is divided by a divisor to obtain a quotient. At least a subset of the quotient is selected as a result. The result is to be used in processing within the computing environment.

A data processing apparatus is provided to perform a digit-recurrence division operation to determine a quotient as a result of dividing a dividend by a divisor. Scaling circuitry scales the dividend and the divisor by a factor to produce a scaled dividend and a scaled divisor. Digit recurrence circuitry performs one or more iterations of the digit-recurrence division operation on the scaled dividend and the scaled divisor, with each iteration producing a digit of the quotient and a remainder value. The remainder value is provided as an input to the digit recurrence circuitry for a subsequent iteration. Initialization circuitry performs a first iteration of the one or more iterations and provides the digit of the quotient after the first iteration. The initialization circuitry receives, as an input, an intermediate value produced by the scaling circuitry while scaling the dividend.
