I have heard that public key encryption and related cryptologies need
32bit processors to execute at a reasonable rate. If this is not true, please correct me.Could someone recommend a cheap 32bit development board, preferably with an ethernet MAC (I should be able to get transceiver, magnetics, and connector if need be).
Also what are the pros/cons of using a MCU with and without a MMU? Is programming significantly more difficult without one?
