The earlier DSPx modules for the KDSP2 product used an ADSP-2184N DSP
chip.  The DSPx for general use, and later modules for the KDSP2 product,
used an ADSP-2185N DSP chip.  If your module uses a 2184, it is a drop-in
for the KDSP2.  If it uses a 2185, it may be drop-in, or it may require
reprogramming the Flash memory chip (the socketed chip).
