Course Instructor: Francisc Iacob, Liviana Nicoleta Tudor

The course introduces basic elements for the number representation in a computer, with fixed point and floating point, arithmetic operations with fixed point and floating point numbers. Also, it allows the understanding of the computer structure and operation. The course accomplishes a description of the functional units of a computer: the control unit, the arithmetic-logic unit, the memory and the input / output subsystem. During the laboratory the students develop some applications achieving numerical processing with numbers represented in user defined format with very high precision.

Syllabus:

• Numerical bases.
• Number conversion from one base to another base.
• Number representation in fixed point direct code, 1' complement code and 2' complement code.
• Addition, subtraction, multiplication and division operations with numbers represented in fixed point.
• Number representation in floating point.
• Addition, subtraction, multiplication and division operations with numbers represented in floating point.
• Elementary computer structure.
• Functional units of computers.
• Arithmetic - logic unit. Memory.
• Control unit.
• Instruction execution in a sequential computer.
• Input / output subsystem.
• The structure of an input / output interface.
• The interrupt system of a computer.
