Implementering av hårdvarustöd för V.42bis kodare/avkodare: Implementation of a hardware support to V.42bis encoder/decoder 2000 (Swedish)Independent thesis Basic level (degree of Bachelor)Student thesis

Abstract [sv]

The v.42bis algorithm is defined by CCITT in 1990 and is an compression standard. In 1997 the v.42bis algorithm was included in the GSM NT standard for cellphones. We have made an hardwareimplementation of the v.42bis algotithm in order to decrease the work for the microprocessor in the cellphone. The hardwareimplementation were made with the hardvare programming language VHDL. In order to verify the design an testplatform was constructed including an microprocessor and two Interface witch communicated with the hardware design and an PC. The Sussenguth- and the LZW-algorithm was used to search the library.
