Lecture 12 Flashcards
What type of MIPS instruction works with registers?
R-Type instructions
What is the difference between a combinational circuit and a sequential circuit?
The output of a combinational circuit is a direct result of its input, whereas a sequential circuit may depend also on its previous outputs.
Can a combinational circuit have feedback loops?
No.
What can a sequential circuit have which combinational circuits cannot?
Feedback loops.
Is an SR NAND latch a combinational or a sequential circuit?
Sequential.
When is the output of an SR NAND latch uncertain?
When S and R both turn from 0 to 1 simultaneously.
What does the clock signal do?
Changes regularly from 0 to 1 and back again.
What is the clock cycle time?
The time the clock signal takes to go from 0 to 1 to 0 again.
