Specific course objectives

This course is meant to address the fundamentals of Boole's algebra, the methods and the tecniques of Analisys and Design of the Logic Networks, both combinatorial and sequential, (asynchronous and synchronous) and a description of the functions of the Arithmetic/Logic Unit in the scenario of the architecture of a numeric processor. The practice lessons are about analysis and synthesis of Logical Networks and algorithms for math operations. They aim to the understanding the functions of the Arithmetic/Logic Unit and its performances. Besides, the teaching introduces the architecture of microprocessors and microcomputers, explaining its behavior by the usage of the Assembly Language. The teaching aims to emphasize the relations among the computer architecture, the microelettronics techniques and the base software organization. The practice lessons are related to the Assembly Language and the tuning of simple programs in a dedicated development environment.
