Note from June 29, 2020
Although we do not yet know how long the social distancing related to the Covid-19 pandemic will last, and regardless of the changes that had to be made in the evaluation of the June 2020 session in relation to what is provided for in this learning unit description, new learnig unit evaluation methods may still be adopted by the teachers; details of these methods have been - or will be - communicated to the students by the teachers, as soon as possible.

Aims

At the end of this learning unit, the student is able to :

1 Given the learning outcomes of the "Master in Computer Science and Engineering" program, this course contributes to the development, acquisition and evaluation of the following learning outcomes:
  • INFO1.1-3
  • INFO2.2-4
  • INFO5.2, INFO5.4, INFO5.5
  • INFO6.1, INFO6.4
Given the learning outcomes of the "Master [120] in Computer Science" program, this course contributes to the development, acquisition and evaluation of the following learning outcomes:
  • SINF1.M2
  • SINF2.2-4
  • SINF5.2, SINF5.4, SINF5.5
  • SINF6.1, SINF6.4
Given the learning outcomes of the "Master [60] in Computer Science" program, this course contributes to the development, acquisition and evaluation of the following learning outcomes:
  • 1SINF1.M2
  • 1SINF2.2-4
  • 1SINF5.2, 1SINF5.4, 1SINF5.5
  • 1SINF6.1, 1SINF6.4
Students completing successfully this course will be able to
  • explain in a practical way the structure of compilers dealing with algorithmic languages
  • design and implement a compiler for a practical language which solves a interesting problem
  • show the interest of compiling techniques in problem resolving
Students will have developed skills and operational methodology. In particular, they have developed their ability to
  • treat rigorously a problem, justifying and validating each step of a project to be able to rely on it to implement the following one
  • explain in practical terms how a source code (Java) is finally translated into byte-code.
  • explain the enforcement mechanisms byte code by JVM
  • explain memory management during the execution of a program
  • explain how garbage collection mechanisms
