    • 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.
    • 提供了一种用于安全和动态地重新配置可重构逻辑的机制。 数据处理系统内的状态机为数据处理系统内的可重构逻辑建立硬件边界,从而形成隔离的可重配置逻辑。 状态机清除分离的可重新配置逻辑中存在的任何先前状态。 状态机验证要加载到隔离可重配置逻辑中的新配置。 状态机确定新配置的认证是否成功。 响应于新配置的认证成功,状态机将新配置加载到隔离的可重配置逻辑中。 状态机然后启动隔离的可重新配置逻辑的操作。
