Desampling using a Cascaded Integrator Comb filter

Been working with a BeagleBoard for the last few months. Can't say much about the project but the Beagle is a nice ARM Linux platform. Finishing up, so now I have more time to update the MHZ100Q sourceforge project page.
I've now added a page describing the ideas behind the Cascaded Integrator-Comb (CIC) filter, and why it makes such a nice desampling filter for a high-rate data acquisition system. Input is 100MHz at 8 bits, and the output is any integer submultiple down to about 1kHz. The hardware resources in the FPGA are low: a set of 64-bit adders and registers, along with a reasonable amount of control logic.
The first version of the page is general description and overview. I plan to put more details of the math behind the CIC. In researching math and html, I found asciimathml.js . It's an open source JavaScript package that lets one embed equations into a webpage's text using simple LaTeX-like strings. I've used it internally and it's really nice to use. Should be live on the mhz100q page in the near future.
