What is in 3D1?
•
An introduction to a ‘bare’ computer system - without
compilers, operating systems, etc.
•
We look at the basic structure or architecture of a typical
microprocessor, the Motorola 68000.
•
We look at the resources available for performing computations.

Assembly Language
•
This is a very low-level language
•
each statement is [almost] exactly equivalent to one
machine instruction
•
A machine instruction is obeyed directly by the machine's
hardware.

Input/Output
•
As well as writing programs, you will find out how a computer
system can interact with objects and mechanisms in the
outside world - i.e. external to the computer.
•
This is Input/Output, or ‘IO’ programming.

Hardware Issues
•
You will be given a fast, brief, introduction to some aspects of
the hardware of the computer — no knowledge of electronics
necessary!

68000 Processor
•
The 68000 is the base member of a family of microprocessors
- 68010, 68020, 68030, 68040, 68060 (?).
•
The 68000 is a kind of ‘CISC’ - a Complex Instruction Set
Computer.
