Expert Solution & Answer
Chapter 12, Problem 23RQ
Explanation of Solution
Comparison on a FIFO register and a LIFO register:
FIFO register | LIFO register |
FIFO is the abbreviation for First In First Out. | LIFO is the abbreviation for Last In First Out. |
FIFO is both an asynchronous and synchronous approach for moving the data from a complete word into a file or stack. | Similarly, LIFO is also an asynchronous and synchronous approach for moving the data from a complete word into a file or stack. |
Here, the first word entered will be the first word coming out. | Here, the last word entered will be the first word coming out. |
In this connection, FIFO Load (FFL) and FIFO Unload (FFU) instructions are used for word loading and unloading process... |
