TSEA81 - Computer Engineering and Real-time Systems

Course Schedule

The course consists of lectures, assigments, labs, and a written exam. The scheduling of the course hours are found in TimeEdit.

There are lecture notes, which contain summarized descriptions of the course topics, and which also provide support for the assignments and the labs. The lecture notes are described in Section Lectures.

There are 6 labs. These are performed during scheduled 2-hour sessions. The purpose of the sessions is to have scheduled occasions for feedback and approval of labs. Lab 5 - Performance analysis, may also require a short written report for its approval.

Note that the actual work required to complete the labs covers more hours than what are scheduled as sessions.

Note that it is required to sign up for the sessions. The sign-up shall be done on the lab sign-up page.

Please see Section Assignments for additional information regarding the labs.

It is required to sign up for the labs. The sign-up shall be done on the lab sign-up page.

Further information regarding the course is found on the course site.


A list of the lectures, with title, contents, week number, and chapter references to the book Realtidsprogrammering, is shown in Table 1. The Lectures page contains links to the individual Lecture notes.
