Abstract

A mechanism for securely and dynamically reconfiguring reconfigurable logic is provided. A state machine within a data processing system establishes a hardware boundary to the reconfigurable logic within the data processing system thereby forming isolated reconfigurable logic. The state machine clears any prior state existing within the isolated reconfigurable logic. The state machine authenticates a new configuration to be loaded into the isolated reconfigurable logic. The state machine determines whether the authentication of the new configuration is successful. Responsive to the authentication of the new configuration being successful, the state machine loads the new configuration into the isolated reconfigurable logic. The state machine then starts operation of the isolated reconfigurable logic.
