Unit Overview

• This unit is about software construction.
• Phases 1 - 3 writing a (cross-)compiler for a
  reasonably simple language.
• Host Jaguar.
• Target M68Ks in real-time lab.
• Programming language C.
• In effect, ANSI C.
• Source language C--
• A subset of ANSII C.
• Target language M68K assembly.

Unit Overview II

• Phase 4 writing a parser for a very simple
  language.
• Host Jaguar.
• Target None.
• Programming language Anything you like.
• Provided that it runs on Jaguar.
• Source language SCL
• The Simple Calculator Language.
• Target language None.

Unit Structure

• Formally
• 12 hours lectures.
• 12 hours directed practical.
• In practice
• About 8 hours lectures.
• Unlimited (almost) surgery sessions.
• Lots of individual work.
• Lots more individual work.

Unit Assessment

• Phases 1 - 3 C--
• Three 5 minute software demonstrations.
• Phase 1 lexical analysis (10)
• Phase 2 syntax analysis (20)
• Phase 3 code generation (10)
• Phase 4 SCL
• Code printout.
• Copy of code on floppy.
• 60

Unit Assessment II

• Marks awarded for
• Functionality.
• How much of C-- and SCL that your programs
  handle.
• Good programming practice.
• Comments, layout, variable names etc.
• Declaring global variables will get you a 0.
• Global constants are OK.

Textbooks

• Dont really need a textbook. Ill tell you
  everything that you need to know.
• If youre really interested this is the classic
  text
• Compilers Principles, Techniques and Tools
• Aho A.V., Sethi R. Ullman J.D.
• Addison-Wesley 1986
• Personally, I wouldnt touch it with a bargepole.
• This is the best book (IMHO) but its out of
  print
• Understanding and Writing Compilers
• Bornat R.
• MacMillan 1979

• Watt D.A. Brown R.F.
• Pearson Education 2000
• This is just a good book
