- Design an 4-to-2 encoder. (You may assume that exactly one input is always true.)
- Design an 8-to-3 encoder. (You may assume that exactly one input is always true.)
- How would you build it from "scratch"?
- How would you build it using two 4-to-2 encoders?
- Design a circuit that takes 3 integers as input and returns the
largest of the three. Assume you have a "greater than" subcircuit. (You may assume that
all three inputs are unique.)
- Design a circuit that performs signed multiplication. Assume you already have a circuit that performs unsigned multiplication. Then add gates before and after this circuit to correctly handle the sign.
- Design a circuit that
increments the hours and minutes on a 24-hour clock. This circuit
has a 5-bit input representing hours and a 6 bit input representing
minutes. It also has a five-bit output representing the updated
hour and a 6-bit output representing the updated minute. The outputs
should represent one minute after the inputs. For example, if the
inputs are 6 and 10, then the outputs should be 6 and 11. If the
inputs are 7 and 59, then the outputs should be 8 and 0. If the
inputs are 23 and 59, then the outputs should be 0 and 0.
