Processor for fine-grain sparse integer and floating-point operations

A processor for fine-grain sparse integer and floating-point operations and method of operation thereof are provided. In some embodiments, the method includes forming a first set of products and forming a second set of products. The forming of the first set of products may include: multiplying, in a first multiplier, a first activation value by a least significant sub-word and a most significant sub-word of a first weight to form a first partial product and a second partial product; and adding the first partial product and the second partial product. The forming of the second set of products may include: multiplying, in the first multiplier, a second activation value by a first sub-word and a second sub-word of a mantissa to form a third partial product and a fourth partial product; and adding the third partial product and the fourth partial product.
