public class InstructionStatistics
A MARS tool for obtaining instruction statistics by instruction category.
The code of this tools is initially based on the Instruction counter tool by Felipe Lassa.

protected void |
addAsObserver()
registers the tool as observer for the text segment of the MIPS program |
protected JComponent |
buildMainDisplayArea()
creates the display area for the tool as required by the API |
protected int |
getInstructionCategory(ProgramStatement stmt)
decodes the instruction and determines the category of the instruction. |
String |
getName()
returns the name of the tool |
protected void |
initializePreGUI()
performs initialization tasks of the counters before the GUI is created. |
protected void |
processMIPSUpdate(Observable resource,
AccessNotice notice)
method that is called each time the MIPS simulator accesses the text segment. |
protected void |
reset()
resets the counter values of the tool and updates the display. |
protected void |
updateDisplay()
updates the text fields and progress bars according to the current counter values. |
