    2. 발표순서 • Why Platform-based Design? • S/W configurable platform의 필요성 • Mobile Platform

    3. 플랫폼(Platform) 인터넷 사회에서는 무엇인가 할만한 틀(frame, 즉 Platform)만 제공해주면 사람들이 몰려들어 그 도구를 이용해 새로운 가치를 제공하는 멋진 것을 만들어 냄. Linux, wikipedia, eBay, Amazon, 싸이월드,… In computing, a platform describes some sort of framework, either in hardware or software, which allows software to run – in Wikipedia Platform : '평평한 장소'라는 프랑스어에서 생겨난 단어

IP can be hard, soft or ‘firm’ (HW), source or object (SW) SW architecture characterisation

    20. Do I need a dedicated DSP ? Which micro- controller? ARM? HC11? ARC? How fast will my user interface software run? How much can I fit onto my microcontroller? Which RTOS do I use? Which scheduling policy do I have to choose ? Which Bus? PI? AMBA? Dedicated Bus for DSP? Can I buy a QCELP decoding core? Do I need a dedicated HW or can I run this on the Microcontroller ? Platform Architecture
