    • Operating system
    • Java Runtime Environment
  • Conclusions



Introduction

  • What is platform?

    • In the literary sense “A raised surface”
    • In the technical sense “Underlying hardware and/or software for a system”
  • We emphasize on the software

  • X-Smiles uses “Java”, hence for executing byte code JRE is required within the platform



Overview of the platform



Overview of the platform (contd..)

  • Java Runtime Environment:

    • Kaffe’s ‘clean-room’ implementation is used
    • For graphical applications, rendering is done using framebuffer
    • Framebuffer provides the high level abstraction of the graphics h/w
    • Vesafb is the framebuffer driver for the Intel architecture, which supports VESA2.0 compliant graphics hardware.
    • 8bpp to 24bpp and 640x480 1600x1200


Conclusions

  • With a working prototype system, the next step is to ‘tweak’ it to achieve better performance

    • Have native decoders for video rendering
    • Currently used JRE does not provide the much needed functionality to support all of the features of the browser
    • Memory foot print and processor load is still under scrutiny
