Dot-products are one of the essential and recurrent building blocks in scientific computing, and often take-up a large proportion of the scientific acceleration circuitry. The acceleration of dot-products is very well suited for Field Programmable Gate Arrays (FPGAs) since these devices can be configured to employ wide parallelism, deep pipelining and exploit highly efficient data paths. In this paper the authors present a dot-product implementation which operates using a hybrid floating-point and fixed-point number system.
