Abstract
In one embodiment, a processor includes a multiply-accumulate (MAC) unit having a first path to handle execution of an instruction if a difference between at least a portion of first and second operands and a third operand is less than a threshold value, and a second path to handle the instruction execution if the difference is greater than the threshold value. Based on the difference, at least part of the third operand is to be provided to a multiplier of the MAC unit or to a compressor of the second path. Other embodiments are described and claimed.
