The real power of the Chameleon is based on its dual processor design. The Chameleon uses an Atmel AVR ATMega 328P as the main master processor (client) and Parallax multicore Propeller chip as the media processor (server). Thus, instead of taxing a single processor system to do everything, the Chameleon offloads all the heavy lifting to the multicore Propeller chip which has 8 processing cores to perform tasks such as generate video, audio, read keyboards and mice, etc.
