Specification and Synthesis of Complex Arithmetic Operators for FPGAs

This paper describes the application of the experimental system LORTGEN for the technology-specific specification and synthesis of high performance arithmetic operators for FPGAs. Using multiplier and adder designs for the XC3xxx-LCA-family as example we demonstrate that the implemented architecture-specific techniques boost the performance and density of the designs. Consequently, LORTGEN enables the implementation of complex operators (e.g. multipliers) in one FPGA, frees the designers from device-specific implementation details and allows them to focus more on actually designing the application.
