Knowing how a real OS works, since the computer boots and initializes the operating system, through the dynamic management of resources, till the the computer is shutdown.
Details of the implementation of some of the basic components of a real OS: initialization code, memory management code, input/output management code, processes management code and upload of executable files code.
Be able to implement some of the basic components of a real OS: initialization code, memory management code, input / output management code , process management code and load executable files code.
This chapter will explain all the actions carried out to start all the operating system services. We also describe and discuss possible implementations of this process in the current operating system.
Mechanisms to enter the system
Describes and discusses the possible implementation of the mechanisms to enter the system along with its hardware support. Important aspects of these mechanisms and dependencies between the operating system and hardware will be detailed. We discuss the benefits of implementing virtualization techniques today. Presents and discusses the various implementations of operating systems today.
This chapter covers the following topics: The logical address space of the process. Page-based memory systems and their hardware support. Design and implementation of virtual memory. Replacement algorithms for virtual memory. Implementation of shared memory. Different memory systems design and implementation in modern operating systems and their hardware dependencies.
This chapter covers the following topics: Detailed Implementation of the process control block. Implementation details for the process of creating processes. Implementation details for the process of finishing processes. Implementation details for the process of loading executables. Implementation details of context switching between processes. Detailed Description of the structures and algorithms for process scheduling. Implementation details of the processes scheduling routines. Description and discussion of various implementations of process scheduling in modern operating systems.
Extending the system kernel
This chapter covers the following topics: Concept, design and implementation of kernel modules of the OS. Loading kernel modules at system initialization time and run time. Description of access to features implemented in kernel modules. Understanding the relationship between kernel modules and physical and logical devices.
Input / output Management and file systems
This chapter covers the following topics: Description and implementation of the OS part independent and dependent of the device. Implementation of a device descriptor. Description, features and implementation of the I/O structures and file systems. Description and implementation of the logical structure of file systems on disk. Communication mechanisms between processes via file systems. Communication mechanisms between processes across the network. Description and implementation of various file systems today.
This chapter covers the following topics: Problems with shared memory between multiple threads of execution within a process. Race conditions. Areas of mutual exclusion. Description and implementation of mechanisms for mutual exclusion in accessing shared memory, in particular, test and set, mutex and semaphores.

The course will have mainly two types of class: theory and laboratories. The theory classes explain the concepts, designs and implementing various components of current operating systems. These classes will be supported by slides.
Laboratory classes will be weekly. During the lab you will design and implement an operating system called Zeos. This project will be done in groups of two people.
The final grade for the course consists of the grade of the core technical competences (CT), and the grade of generic competence (CTr) by the formula:
Final Grade = (CT + CTr) * (10/11)
Where the maximum score of CTr is 1.
The grade of the CT can be obtained by continuous assessment (CTc) or excepcionally by a final exam (CTf). Is calculated as:
CT = max (CTc, CTf)
Where CTc grade is evaluates the theory (T) and laboratory (L) components. The formula for calculating this grade is as follows:
CTc = 40% T + 60% L
To calculate T two assessments are used with the same weights:
T = 50% T1 + 50% T2
To calculate L, an exam (L1), a follow up grade (S) and a project (P) is used, with the following weights:
L = 30% L1+ 20% S + 50% P
The follow up grade (S) is assigned by the teacher as an evaluation of the right progress throughout the laboratory.
The project grade (P) corresponds to the design, follow up and final implementation of the project.
The CTf grade is calculated using a theory exam (T) and a laboratory exam (L). To accomplish this grade is mandatory to do both exams. This option is only available for those students that fail the continuous assessment. The formula is as follows:
CTf = 50% T + 50% L
The grade of generic competence (CTr) is obtained during the semester through various activities. Rating of this competence will have values A, B, C, D or NA: A corresponds to an excellent level, B to a desired level, C to a sufficient level, D to a failed level, and NA to not assessed.
The student must have the technical capabilities that will confer the subjects studied previously together with a medium level of technical English to read and understand documentation.
The technical capabilities could be summarized as follow:
-Operating systems: Understanding the basics of an operating system along with the creation of applications using the generic system call interface explained during the Operating System course.
-In terms of computer architecture: Knowledge of the main elements of a computer, how these elements relate to each other, internal representation of data and knowledge of the assembler language.
-In terms of programming: Ability to code complex programs from scratch composed of several moduls. Definition of data types, pointers and references, and assembler code. Compilation and linkage of executables.
NO HI HA CANVIS RESPECTE LA INFORMACIÓ PUBLICADA A LA GUIA DOCENT
L'assignatura serà 100% no presencial. Les classes de teoria i laboratori es faran via Google Meet, convocada previament al Racó de la FIB, i seran síncrones (durant l'horari normal de classes). Eventualment, es podríen fer algunes sessions presencials i sempre seran convocades amb temps suficient a l'estudiantat.
Totes les proves avaluatives que formen part de l'avaluació continuada, seran no presencials i es convocaran amb temps suficient als estudiants junt amb les seves normes.
El mètode d'avaluació serà el mateix que es pot trobar a la guia docent.
