Abstract: An accelerator card can include a read-only memory configured to store a security identifier in a designated field therein and a satellite controller configured to read the security identifier in response to a reset event. The satellite controller is configured to select, based on the security identifier, a security mode from a plurality of security modes and implement the selected security mode in the accelerator card.

Abstract: Systems and method for synchronizing access to buffered data are disclosed. In such a method, video data is buffered in a frame buffer memory by a producer device. A write level indicator is provided to a synchronizer by the producer device. A read level indicator is provided to the synchronizer by a consumer device. The synchronizer compares the write level indicator with the read level indicator to determine a difference. The consumer device is informed by the synchronizer when the difference meets a sub-frame threshold. The consumer device reads the buffered data from the frame buffer memory on a sub-frame-by-sub-frame basis responsive to the informing.
