Homework 1
UCR EE/CS120B: Introduction to Embedded Systems
Fall Quarter 2002, Prof. Frank Vahid

Due Thursday October 17 at the *beginning* of lecture.

Note: I strongly encourage you to work with your fellow students, 
but also be sure to turn in your own original work for every problem.

1. Design a 4-bit register with four outputs Q3, Q2, Q1, Q0, with the 
   following control inputs: ld (load 4 input bits I3, I2, I1, I0), 
   decrement (subtract 1), and clear (load in all 0s).
    
2. ESD 2.12

3. ESD 2.14

4. ESD 2.22

5. Design a circuit with inputs A, B, C, D, E, F that computes 
   A*B + C*D + E*F. However, your circuit can only use one adder and
   one multiplier. Start with an algorithm written in C such that no
   single statement or expression contains more than one multiply and
   one addition, convert the algorithm to an FSMD, separate the FSMD 
   into an FSM and a structural datapath, and then implement the FSM as 
   a structural circuit.
