• receiving, at a computer, instructions and data in a Von Neumann format;
• converting the instructions and data to a Harvard format;
• and
• executing the instructions and data in the Harvard format.

A system comprising:

• a harvardizer configured to receive comingled instructions and data and produce separated instructions and data;
• a data memory configured to receive the separated data;
• an instruction memory physically separate from the data memory, the instruction memory configured to receive the separated instructions;
• one or more processors configured to execute the separated instructions and data, the one or more processors including one or more transformation execution engines configured to execute legacy code configured in a Harvard format;
• one or more encryptors configured to encrypt the separated instructions and data from the harvardizer, send the encrypted instructions to the instruction memory, and send the encrypted data to the data memory;
• one or more decryptors configured to decrypt the encrypted instructions and data.
