The system or device may build one or more data packets by dividing a given payload for a packet into data blocks and inserting data checks for each data block sequentially into the packet payload. The device may generate, for each of the data blocks, a corresponding data check block corresponding to data in each data block. The device may send or arrange the data blocks and the corresponding data check blocks such that each of the data blocks is followed by the corresponding error check block in the packet. Using the corresponding check block, each of the data blocks is independently verifiable, so that the data blocks may be used upon receipt, even if the payload is not completely received.

Method and system for sequencing data checks in a packet

Traffic control logic is provided to support a plurality of channels on a link. A plurality of reserved credit counters is provided to each identify reserved flow control credits for a corresponding one of the plurality of channels. Further, a shared credit counter is provided to identify shared flow control credits to be shared between two or more of the plurality of virtual channels.

Shared flow control credits

In one embodiment, the present invention includes a system on a chip (SoC) that has a first agent with an intellectual property (IP) logic, an interface to a fabric including a target interface, a master interface and a sideband interface, and an access control plug-in unit to handle access control policy for the first agent with respect to incoming and outgoing transactions. This access control plug-in unit can be incorporated into the SoC at integration time and without any modification to the IP logic. Other embodiments are described and claimed.
