Summary: | A computer has user IDs stored in a ROM, and user passwords associated with each stored user ID. A command from the CPU directs a coprocessor in the computer to read a password for a first ID. The coprocessor compares the password entered by the user with the password for the first ID. If the entered password matches the password for the first ID, the coprocessor reports that the password for the first ID was entered correctly. If the entered password does not match the password for the first ID, the coprocessor compares the entered password with a password for a second ID. If the entered password matches the password for the second ID, and if the second ID dominates the first ID, the coprocessor reports that the password for the first ID was entered correctly If the entered password does not match the password for the second ID, the coprocessor compares the entered password with a password for a third ID. If the entered password matches the password for the third ID, and if the third ID dominates the first ID, the coprocessor reports that the password for the first ID was entered correctly. This process continues until a match is found or there are no user IDs remaining. |
