A data processing system is disclosed that includes an Input/output (I/O) interface to receive incoming data and an in-line accelerator coupled to the I/O interface. The in-line accelerator is configured to receive the incoming data from the I/O interface and to automatically remove all timing channels that potentially form through any shared resources. A generic technique of the present design avoids timing channels between different types of resources. A compiler is enabled to automatically apply this generic pattern to secure shared resources.
