The Cascade Demodulator is a self-contained unit composed of a high speed digital signal processing board, an RF front end, and an electronic power conditioner, all contained in a modular chassis.  Analog samples are taken at 525 MHz and are passed on to a reconfigurable FPGA where the DSP algorithms implement the demodulation process.  A high speed serial link sends the demodulated data to a Solid State Mass Memory.  The architecture chosen to implement this mission is the result of an evolution in DSP architectures, and has resulted in a general purpose space qualified reconfigurable DSP platform, which can be used for many other applications. 

In this paper we shall discuss the following :
