Hello
I need information about creating a fast adder (n = n + 1) and a fast equal (a = b). (both 28 bit signals)
I'm going to create a fast binary counter in a FPGA Spartan II
Would it be faster to create several 4 bit LFSR and a converter to binary than a normal binary counter?
I need the binary output because it's a timestamp
I need to be able to reset the counter to zero when it reaches a certain number. (reset every second by a pulse per second signal or if the reference signal is missing when the counter is equal to the measured frequency of the clock)
The goal is to use a clock frequency on 100MHz + 25% margin.
Thanks Rune
