public class HardNodeDemo
extends HardNode

This gives an example of a HardNode. It simply takes data from the "east" input, increments it, then sends it to the "west" output.

execute

public void execute(int instr)
             throws MemoryAccessException,
                    IllegalRegisterException

Description copied from class: Processor

This method is called after the fetch() and decode() and represents the execution phase of the instruction. All update of processor state occurs in this method. This is where most of the processor definition will occur. See examples for suggestions on implementation of this method.

Specified by:

execute in class Processor

Parameters:

instr - The instruction to be executed.

Throws:

MemoryAccessException - A Memory Access Exception is thrown is an illegal memory access is attempted.

IllegalRegisterException - if an attempt is made to access a register illegally.
