Hi.

First i wanna mention, im a complete noob at this.

I've got this assignment where im to design a circuit, which takes a positive 4bit number A and multiply it with + / - 10(des)

I've tried googling it without any luck.

Can anyone help me?
Any pointers?

much appriciated

 

10(des) is that meaning decimal?

You could implement a successive adder to perform the multiplication:
e.g. 3*10 = 10 + 10 + 10 = 30, a Booth multiplier, or you could try a combinational approach like discussed here...

yes, im supposed to multiply any 4bit number with 10, and design the circuit for it, but thus far im still all dead i dunno how to start and where to start.

i checked your link, it seemed far too complicated

Then i would suggest taking the successive-addition route. A simple FSM can do this...

What kind of circuit are you expected to come up with? Combinatorial or sequential?
