Advanced Optimisation Techniques for C

Course id: 0070

Synopsis

C is the programming language of choice for the vast majority of embedded applications, and will be the dominant language for the foreseeable future with the increasing demand for ever sophisticated, miniature and intelligent appliances.

This course is specifically tailored for engineers intending to optimised their C code for maximum performance. The topics covered are suitable for a wide range of system from resource constrained microcontroller-based systems to computers. The techniques discussed are equally applicable to C++, and a section is dedicated to it.

Course highlight
Participants will be able to optimise their own code as part of the course.

What participants say about the course
The following are some verbatim statements from the participants:

Improved my programming skills -- Nov 2014
This course is meet our expectation -- Nov 2014

What you will learn

This course concentrates on the theoretical and practical knowledge to allow participants to achieve the following learning outcomes. Upon completing the course, participants would be able to:

Identify and mitigate bottlenecks in algorithms
Use efficient data types and employ efficient operators
Efficiently pass parameters to functions
Reduce computation overheads of array and structure access
Unroll loops for increased performance

Who should attend

This course is particularly suited for design engineers, application engineers, software engineers and programmer responsible for optimising systems.

Prerequisite

Participants must have C programming experience and know the basic architecture of computing systems (processor, memory, fetch, execution).

Course methodology

This course is presented in a workshop style with example-led lectures interlaced with hands-on practical for maximum understanding. Participants would be able to optimise their code under the guidance of the instructor.

Course duration

2 days.
