Abstract: A processor-implemented data processing method includes: normalizing input data of an activation function comprising a division operation; determining dividend data corresponding to a dividend of the division operation by reading, from a memory, a value of a first lookup table addressed by the normalized input data; determining divisor data corresponding to a divisor of the division operation by accumulating the dividend data; and determining output data of the activation function corresponding to an output of the division operation obtained by reading, from the memory, a value of a second lookup table addressed by the dividend data and the divisor data.

Abstract: Message splitting and aggregation in a multi-stage electrical interconnection network are disclosed. A method of operating an electronic device comprised of computing devices, includes splitting, into segments, a message to be transmitted from a first of the computing devices, transmitting the segments to a second of the computing devices through a multi-channel that is based on an electrical connection between the first computing device and a plurality of switches, wherein the multi-channel includes channels respectively including electrical connections, the electrical connections connecting the first computing device with the second computing device, and reconstructing the message by aggregating the segments in the second computing device, wherein a bandwidth of the multi-channel transmitting the segments is greater than a maximum bandwidth of a single electrical connection of the electrical connections.

Abstract: A method of operating a hardware accelerator, includes loading a lookup table, mapping each of input data values of input data to an index of indexes in the lookup table based on an input data distribution of the input data, and obtaining output data values corresponding to the input data values using the lookup table. The output data values are proportional to corresponding softmax values of the input data values.
