• Machine Levels: Computer organization can be modeled as a hierarchy of levels starting from the hardware (digital logic level) working upward to micro-architecture, machine code (Instruction Set Architecture) etc. A function on a given level is implemented by a set of functions on the level below
• Von Neumann Architecture: what do we mean by von Neumann architecture?
• An Overview of the History of Computers. A brief list of important, people, computers, and events in the history of computers.
  
• From the U.S. Constitution to IBM:  How the problem of the 1880 census indirectly led to the formation of IBM - a demonstration of how the need for data procession drove the development of the computer.
• Two's Complement Wheel: a graphical example of how twos complement representation works. 
• Multiplication and Division of Binary Integers.
  
• An Overview of the Architecture of the PDP-8: updated 09/01/02. A zip file containing an executable copy of the PDP-8 Emulator program can be downloaded by clicking here.
• PDP-8 Assembler: A brief description of PDP-8 assembler and how assemblers work
• IEEE Standard 754 for Floating Point Numbers: A useful website from the Pittsburg Supercomputing Center 
• Companion Website to Murdocca & Heuring's Computer Architecture and Organization: An Integrated Approach (CAO)
• The ARC Instruction Set ARC stands for "A RISC Computer", an architecture based on the SPARC (Scalable Processor Architecture) developed at SUN Microsystems in the 80's
  
• A Java Byte Code Engine: A simulator that allows the user to assemble and run a subset of Java Byte code. The Java Engine Manual provides documentation for the assembler and simulator as well as a list of the Java Byte Code instructions used by the Java Engine.
  
• An Introduction to the Intel 80x86 Architecture: including an introduction to writing Intel 80x86 assembler
• An Introduction to MS-DOS: a simple command line operating system that "works" within a Command Prompt window.
• Quick & Dirty Debug: A brief one page cheat-sheet for using DEBUG
  
• Memory : basic structure of main memory, big-endian vs little endian memory, error-correcting codes, basic cache issues.
• Disk I/O: Physical and logical organization of a floppy diskette including a partial list of Intel 80x86 INT 13h, 21h, 25h, and 26h instructions for disk I/O.
• Intel 80x86 Branching: A brief introduction to conditional and unconditional branching on the Intel 80x86 architecture.
• Boolean and Arithmetic Instructions on the Intel 80x86: Shifts, rotates, boolean and arithmetic instructions plus code to read and write hexadecimal and decimal integers.
• Processors: Fetch-Execute Cycle, Datapaths, RISC vs CISC, and Pipelines
  
• Addressing Modes: Methods to calculate the effective address of an operand.
• Subroutines and Interrupts: What they are and how they are implemented on the Intel 80x86 and PDP-8 architectures.
• Parameters. Links to .pdf documents on parameter passing on the PDP-8 (using parameter slots) and on the  Intel 80x86 (demonstrating four different approaches but concentrating on using the stack)
