Expert Solution & Answer
Chapter 5, Problem 19E
Explanation of Solution
Tradeoffs between static and dynamic branch prediction:
- The static prediction obviously avoids chip-area and run-time energy costs...
Explanation of Solution
Advantage and disadvantages of static branch prediction:
Advantage:
- It uses backward branches which has a target address that is lower than its own address.
- It can use as a backup even if dynamic schemes are used.
Disadvantage:
- It must kill the instructions in the pipeline when a bad decision is made.
- Speculatively issued instructions must not change processor state...

8. Cash RegisterThis exercise assumes you have created the RetailItem class for Programming Exercise 5. Create a CashRegister class that can be used with the RetailItem class. The CashRegister class should be able to internally keep a list of RetailItem objects. The class should have the following methods:
A method named purchase_item that accepts a RetailItem object as an argument. Each time the purchase_item method is called, the RetailItem object that is passed as an argument should be added to the list.
A method named get_total that returns the total price of all the RetailItem objects stored in the CashRegister object’s internal list.
A method named show_items that displays data about the RetailItem objects stored in the CashRegister object’s internal list.
A method named clear that should clear the CashRegister object’s internal list.
Demonstrate the CashRegister class in a program that allows the user to select several items for purchase. When the user is ready to check out, the…

Discuss the OSI model's physical layer specifications when designing the physical network infrastructure for a new office.arrow_forwardIn a network, information about how to reach other IP networks or hosts is stored in a device's routing table. Each entry in the routing table provides a specific path to a destination, enabling the router to forward data efficiently across the network. The routing table contains key parameters determining the available routes and how traffic is directed toward its destination. Briefly explain the main parameters that define a routing entry.arrow_forwardYou are troubleshooting a network issue where an employee's computer cannot connect to the corporate network.
