Objectives

BACKGROUND

The PC-compatible desktop and mobile platforms are an everyday tool in modern societies. Their architecture reflects the current technological development, but also defines the limits of the computer's capabilities and performance. Variants of the ARM instruction set are used today n most mobile platforms (tablets, mobile phones)in use today. Both system architecture and ISA have a deep impact on the day-to-day practice of informatics engineers.

SPECIFIC AIMS

The course unit Microprocessors and Personal Computers aims to develop, combine and apply concepts in the areas of Computer Architecture and Programming Languages. On the one hand, the course explores the relationships between the CPU instruction set and low-level programming (assembly language). On the other hand, recognizing that the architecture of modern personal computers goes far beyond the architecture of the CPU, the course addresses the general architecture of a computational platform, including data storage subsystem and other peripherals. The discussion is based on the ARMv8 64-bit CPU architecture. Upon successful completion of this course, students will have acquired the ability to identify and describe the architecture of the computational platforms in use today, as well as the ability to apply assembly programming to the implementation of algorithms.

PERCENTUAL DISTRIBUTION

• Scientific component: 60%
• Technological component: 40%

Learning outcomes and competences

After completing this course, students will be able to:

• Identify and describe the major subsystems of a personal computer;
• Describe and assess the performance of data storage systems (magnetic disks);
• Describe, select and evaluate the performance of different methods of communicating with peripherals (polling, interrupts, DMA)
• Explain the principles of operation of buses for communication with peripherals.
• Explain and evaluate the contribution of each subsystem to the overall performance;
• Use tools for compiling and debugging (assembler, debugger);
• Describe the architecture of instruction set ARMv8 (64-bit version);
• Develop short programs in ARMv8 assembly language ;
• Explain the operation of programs written in ARMv8 assembly language;
• Explain the mechanisms for invocation of subroutines;
• Use modular subroutines to implement programs;
• Use floating-point instructions;
• Employ SIMD instructions for explicit exploitation of data parallelism;
• Establish a correspondence between assembly code and C/C++ source code.

Teaching methods and learning activities

Theoretical classes: Oral presentation of the different topics of the course. This presentation will be supported, when possible, with examples and its discussion.

Practical classes: The methodology of the practical classes is based in the presentation, discussion, and resolution of problems that will be tested on a computational platform or CPU emulator.

Eligibility for exams

The student cannot miss more than 25% of the planned practical sessions.

Only students that already attended more than 75% of the planned practical sessions last year (2017/18) are not subject to this requirement.

Calculation formula of final grade

Student evaluation has the following components:

• Two tests (M1 and M2)
• Final exam

Missing components count as zero.

The two tests make up the distributed evaluation.

The tests have two parts: 1) multiple-choice questionnaire, with a duration of 45 min (closed book); 2) open questions or written programming exercise (45 min).

The grade for the distributed evaluation (DE) is given by:

DE = (M1 + M2)/2

For students that attended the course in 2017/18, the corresponding grade for the distributed evaluation may be used.

The final grade is given by:

Final grade= maximum(0.5 x exam + 0.5 x DE; exam grade)

For successful completion of the course unit, the student must fullfil all the following conditions:

• Grade for distributed evaluation equal to or greater than 5.0 (in 20) in the current or in previous years;
• Exam grade equal to or greater than 5.0 (in 20);
• Final grade (rounded to units) equal to or greater than 10 (in 20).

Closed-book exam, duration of 2:00H

Classification improvement

The course  grade can be improved by taking the appeal exam (similar to the regular exam).

Observations

The development of microcomputer applications requires knowledge of computer architecture, microprocessors, low-level programming languages (assembly) and interfacing to external physical devices. This course unit comes in course plan after the course “Computer Architecture and Organization” and its objective is to develop and apply these concepts in the context of the ARMv8 architecture.
