Abstract [en]

The aim of this report is to give a description of a diploma work of 20 points that has been performed during the spring 2006 at Ericsson AB in Borås. The report accounts for the problem and procedure during the diploma work. The software used for this project was embedded in a radio link. The RAM in this radio link was divided into several regions where two were used for memory allocation. The current allocation of memory in the radio link was not optimized with regards to performance, security and memory use and the configuration used made it difficult to determine the memory use of the system and the actual memory need. Furthermore, no garbage collection existed; this resulted in fragmentation and reduction in performance arising over time. The objective of the diploma work was to optimize the allocation of memory in the radio link's software and being able to measure the processor load and memory use. The project was managed according to a work method where UML-diagrams were used and the project deliverables were defined according to a process specification from Ericsson AB. The project was time-limited and has been performed in ten weeks by two students. The project was divided up in three iterations, each iteration consisting of a number of tasks. A milestone is set after each at which the intended tasks are validated and done with. An application fulfilling these requirements was developed, using C#.NET and Visual studio 2005, and that presents its results graphically. It is applicable in development, error search and verification of the radio link's software. ANSI-C and x86-assembler were used for development and modification of the software that is being executed in the radio link. Due to secrecy policies at Ericsson AB the report has been censored and the removed sections replaced with […].
