WHAT IS THE DIFFERENCE BETWEEN CM1K AND NM500
The neurons of the NM500 and CM1K have the exact same behavior and use the same registers from 0x00 to 0x0F.
The following table presents their differences.
Adapting a hardware design to migrate from the use of the CM1K to the NM500 should be easy.
Combining the use of both types of chips in a same architecture is also possible provided that the slowest clock of
the two is in effect.
