Von Neumann Internal Organization of the Computer Architecture and Assembly-Level Code

IJVM is a machine-level coding in assembly language that will allow you to convert code from Java and C++ object-oriented programming (OOP) languages into machine assembly code. Hint: Remember for a Java statement such as m = m +2; it requires three IJVM statements from (IPUSH, IADD) to execute the instruction by the assembler.

Part 1: Using what you have learned about IJVM, convert the following Java code into IJVM. Submit the code in a written document.

k = j + l;

If (k == 4)

L = 16;

else

j = j - 2;

Part 2: In a written document, address the following topics in relationship to the code you just converted:

• How are the instructions represented at both the machine level and in context of a symbolic assembler?
• Explain the different instruction formats in terms of fixed and variable length.
• How are these instructions executed in a classical von Neumann machine?
