    I'm working on a personal project for a friend, and I realize that I'm in over my head.
    I'm wondering if anyone would be willing to lend a hand in helping me design a 4bit multiplier.

    Information about project:
    Can only use the following components-

    *D Flip-flops (74LS74A)
    *1 4-bit Up/Down Counter (74LS169)
    *1 4-to-1 MUX (74LS153)
    *1 4-bit Adder (74LS283)
    *2 4-bit Parallel Shift Registers (74LS194A)
    *Various NAND/AND/OR/NOT gates

    After doing some research I've figured out the basic setup of the circuit. I've thrown together a basic layout (attached) of how I feel it should work. The layout however is incomplete, and I'm having trouble understanding where the controller comes into play and how to design the controller itself using what components I have.

    Any help is greatly appreciated!
