public class BHTSimGUI
extends JPanel

Represents the GUI of the BHT Simulator Tool.

The GUI consists of mainly four parts:

• A configuration panel to select the number of entries and the history size
• A information panel that displays the most recent branch instruction including its address and BHT index
• A table representing the BHT with all entries and their internal state and statistics
• A log panel that summarizes the predictions in a textual form
