Abstract
A hardware processing unit is provided. The hardware processing unit includes: an accumulator; a multiplier-adder receives first and second factors and receives an addend, the multiplier-adder generates a sum of the addend and a product of the first and second factors and provides the sum; a first multiplexer receives a first operand, a positive one, and a negative one and selects one of them for provision as the first factor to the multiplier-adder; a second multiplexer receives a second operand, a positive one, and a negative one and selects one of them for provision as the second factor to the multiplier-adder; a third multiplexer, having an output, that receives the first operand and the second operand and selects one of them for provision on its output; and a fourth multiplexer receives the third multiplexer output and the sum and selects one of them for provision to the accumulator.
