Multiple Constant Multiplication Optimizations for Field Programmable Gate Arrays

This work covers field programmable gate array
(FPGA)-specific optimizations of circuits computing the multiplication of a
variable by several constants, commonly denoted as multiple constant
multiplication (MCM). These optimizations focus on low resource usage but high
performance. They comprise the use of fast carry-chains in adder-based constant
multiplications including ternary (3-input) adders as well as the integration
of look-up table-based constant multipliers and embedded multipliers to get the
optimal mapping to modern FPGAs. The proposed methods can be used for the
efficient implementation of digital filters, discrete transforms and many other
circuits in the domain of digital signal processing, communication and image
processing.
