  4. 3. Development of a low power hand-held device in a low budget manner

    Magister-uppsats, Institutionen för systemteknik

    Författare :Anders Kagerin; Michael Karlsson; [2006]
    Nyckelord :Embedded; Hand-held; FLAC; Development; Hardware; Software; Device; Codec; Decoder; MP3; Ogg; WMA;

    Sammanfattning : The market of portable digital audio players (DAPs) have literally exploded the last couple of years. Other markets has grown as well. PDAs, GPS receivers, mobile phones, and so on. This resulted in more advanced ICs and SoCs becoming publically available, eliminating the need for in-house ASICs, thus enableing smaller actors to enter the markets. LÄS MER
