This note covers the following topics: Introduction to Computer Organization,
Sample 68000 Addressing Modes, Introduction to Input/Output, Memory
Mapped I/O, Stacks and Stack Operations, Stack Related Instructions,
Recursive/Re-entrant subroutines, Utilizing The Stack for Local Subroutine
Storage, Interrupts & Exceptions,
Interrupt-Driven I/O, Vectored Interrupts, PIT I/O and Timer Interrupt Examples,
68000 Binary Coded Decimal (BCD) And Multiple-Precision Arithmetic Support , Reduced Instruction Set Computer, Basic concepts of CPU organization.
The purpose of
this book is to give the reader a better understanding of how computers really
work at a lower level than in programming languages like Pascal. By gaining a
deeper understanding of how computers work, the reader can often be much more
productive developing software in higher level languages such as C and C++.
Learning to program in assembly language is an excellent way to achieve this
goal.
