ABSTRACT:
A system for the encryption and decryption of data employing cycle stealing to accelerate data processing operations. The cycle stealing is employed by using level sensitive latches in a microcode controller system for storing addresses and code words. The microcode controller system controls the data path hardware for executing the encryption/decryption operations.
