2. A register's ___ provide information to the control FSM about the register's contents.
a) status outputs b) control inputs c) clock inputs d) data inputs
3. A register with unencoded control signals ___.
a) will have fewer control signals coming from the control unit, compared to a register with encoded control signals.
b) will have more control signals coming from the control unit, compared to a register with encoded control signals.
c) will have more status signals going to the control unit, compared to a register with encoded control signals
d) will have fewer status signals going to the control unit, compared to a register with encoded control signals.
4. An FSM that generates register control signals ___.
a) will not be able to control the registers unless it is a Mealy machine.
b) could be either a Mealy or Moore machine; there is no advantage to one or the other
c) should be a Mealy machine
d) should be a Moore machine
Explanation / Answer
1. Bit width
The number after slash indicates the number of paths present in a bus.
2. control inputs read/write
3. will have more control signals oming out of the control unit, compared to a register wih encoded control signals
