Abstract : This paper presents integer multiplication and division operators dedicated to Virtex-II FPGAs from Xilinx. Those operators are based on small 18 x 18 multiplier blocks available in the Virtex-II device family. Various trade-offs are explored (computation decomposition, radix, digit sets, ...) using specific VHDL generators. The obtained operators lead to speed improvements up to 18% for multiplication and 40% for division compared to standard solutions only based on CLBs.
