Hi am new to the world of electronics. I am trying to designing a Digital Tachometer that displays from 700-4000 rpm +/- 50. I am working from a very basic level so all my work is with simple clocks, counters etc.. At the point i am at i have a clock measuring my rpm every 6 seconds. My question is being that I have a measurement every 6 seconds i need to multiply it by 10 to get rpm. I am confused as to how to multiply my binary number by 10 and then convert that binary number to decimal in vhdl. any help or direction would be greatly appreciated thank you.
