this is a Geode

The hardware is slow. You need to take advantage of what little you have, rather than wasting CPU cycles (including memory access -- there is barely any cache) on thick abstraction layers and other fluff. What you get:

  • MMX
  • 3dNow!
  • an extra Geode-specific instruction for vector square root

Don't be afraid of assembly. Assembly is good for you. It builds character.

Meeting minutes 10Sep07 , 1330hrs

  • Things TODO:


  1. Explore OpenSound Toolkit - explore how sound objects work, what filters it already provides, how to configure new filters and how viable (in terms of extra packages required) it would be to use OpenSound toolkit on the XO.
  2. Get sugar-jhbuild running - Sugar_with_sugar-jhbuild
  3. Explore TamTam
  4. With the help of 1 and 3 define goals of application and general UI layout
  5. Read up on how to do basic sound processing in python
  6. Use MATLAB to test out mathematical operations.


  • Implementation basics
  1. gstreamer
  2. cairo
  3. pygtk


  • Attended by Hemant, Asim and Arjun
