2 Computer organization Encompasses all physical aspects of computer systems. E.g., circuit design, control signals, memory types. How does a computer work? Computer architecture Logical and abstract of system implementation as seen by the programmer. E.g., instruction sets, instruction formats, data types, addressing modes, memory access methods, and I/O mechanisms. How do I design a computer? Principle of Equivalence of Hardware and Software : Any task done by software can also be done using hardware, and any operation performed directly by hardware can be done using software.* Computer Organization vs. Architecture * Assuming speed is not a concern.
