soundarthot chameleon: an audio DSP engine
  DSP Module

Sound Art Hot Chameleon Audio-DSP - System: A programmable studio device with integrated signal processor with exchangeable firmware.  Various modules like synthesizer, compressor, stereo processor and delay are available.  The hardware consists of a Motorola cold fire-CPU (MCF5206e), similar to 68000 with 32Bit support and the Motorola 56303, a digital signal processor of the 56k type.  Furthermore there is additional periphery like AD-converters and DA-Converters, potentiometers, knobs, buttons and LEDs + a job wheel.

I ported some of the algorithms for virtual analog modeling formerly developed for TMS320 to chameleon.

A current project with the chameleon is echo cancelling

 In the meanwhile some algorithms to a FPGA platform:
