fpga fast adder
I found that a 16bit adder in Spartan3 FPGA have a delay of about 6ns.
But the embeded 18bit multiplier in Spartan3 FPGA have a delay of only 8 ns.
I want to do a multiplication followed by a addition in 1 clock time,so i need to reduuce the delay of adder.
Can anybody give me some advice? Thanks
