  2. 1. Custom Designed Digital Signal Processors Using Bit-Serial Arithmetic

    Author : Peter Nilsson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; On-Chip Clocking; Digital IF-Filtering; Digital Wideband Filtering; Elektronik; Electronics; Bit-Serial Arithmetic; CMOS; Custom DSP; VLSI;

    Abstract : This thesis presents two prime contributions. First, digital filters for both intermediate and base band filtering for mobile communication are presented. Second, a local clock for on-chip clock generation is introduced. The intermediate frequency filter is a digital alternative to today's analog filters. READ MORE

  4. 2. Custom Datapaths for DSP ASICs Methodology and Implementation

    Author : Pontus Åström; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik; handshake circuits; design patterns; design abstraction; design methodology; UMTS; interleaver architecture; Turbo decoder implementation; low power; Digital filter; wave digital filter;

    Abstract : This thesis regards datapath design and analysis at several abstraction levels. Five papers are presented that focus on datapath design for mobile communication systems and design methodologies for such datapaths. Paper I discusses different aspects of Turbo channel decoder design for high speed and low power applications. READ MORE

  5. 3. Hardware for speech and audio coding

    Author : Mikael Olausson; Viktor Öwall; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : While the Micro Processors (MPUs) as a general purpose CPU are converging (into Intel Pentium), the DSP processors are diverging. In 1995, approximately 50% of the DSP processors on the market were general purpose processors, but last year only 15% were general purpose DSP processors on the market. READ MORE

  6. 4. Methods for collecting and analysing simultaneous strain and moisture data during wood drying

    Author : Jonas Danvind; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träfysik; Wood Physics;

    Abstract : Improved understanding of moisture and mechanical behaviour is an international objective for wood drying research. The main objective of this licentiate thesis work was to develop an experimental method suitable for collecting valuable response data related to the moisture and mechanical behaviour of drying wood.

  7. 5. Aspects of system-on-chip design for FPGAs

    Author : Andreas Ehliar; Lars Svensson; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Due to the increasing NRE costs of recent ASICs, the use of FPGAs is expected to continue to increase. While the first FPGAs were limited devices useful mainly for glue logic, todays FPGAs are highly capable devices used in many different application areas including telecommunication, multimedia, medical, and automotive.
