Aim: Learn programming at assembly level including microprogramming.
Method: Use a hypothetical instruction set to do a simple assembly level programming. Do microprogramming for a simple instruction.

Lecture

   Assembly 1 : data path, assembly language, assignment, if..then
   Assembly 2 : while, for, call to a subroutine S2 ISA   S2 examples
   Microprogramming
   Previous lecture on assembly language (2003)

Assessment:

A test assembly language programming by

1 Given a high level language construct, translate it into an assembly language of a given instruction set.
2 Given an assembly language program, deduce its output, determine its behaviour. The typical questions will be
a) what is in the register after executing this program?
b) how many times the program execute this loop?

B Given a data path and an instruction, complete with all signals and microprogram format, write a microprogram sequence for an instruction.
