摘要： In one embodiment, the present invention is directed to method for receiving a packet in a first agent, where the packet includes a first packet header with an expanded header indicator. Based on this indicator, the agent can determine if the packet includes one or more additional packet headers. If so, the agent can next determining if it supports information in the additional packet header based on a header identifier of the additional header. Other embodiments are described and claimed.

摘要： In one embodiment, the present invention includes a method for handling a request received in an agent designed in accordance with a peripheral component interconnect (PCI) specification using PCI Express™ semantics. More specifically, responsive to determining that the agent does not support the request, an unsupported request detection register of the agent can be updated, and a response sent from the agent to indicate that the agent does not support the request. Other embodiments are described and claimed.

摘要： In one embodiment, a system on chip includes a first endpoint to issue a non-posted memory write transaction to a memory and a Peripheral Component Interconnect (PCI)-based fabric including control logic to direct the non-posted memory write transaction to the memory, receive a completion for the non-posted memory write transaction from the memory and route the completion to the first endpoint. Other embodiments are described and claimed.

摘要： According to one embodiment, a system on a chip includes multiple agents each corresponding to an intellectual property (IP) logic and a fabric to couple the agents. The fabric can include a primary message interface and a sideband message interface. The fabric further includes one or more routers to provide out-of-band communications between the agents via this sideband message interface. To effect such communication, the router can perform a subset of ordering rules of a personal computer (PC)-based specification for sideband messages. Other embodiments are described and claimed.

摘要： In one embodiment, a method includes determining whether producer-consumer ordering rules have been met for a first transaction to be sent from a source agent to a target agent via a fabric, and if so a first request for the first transaction is sent from the source agent to the fabric in a first clock cycle. Then a second request can be sent from the source agent to the fabric for a second transaction in a pipelined manner. Other embodiments are described and claimed.

摘要： In one embodiment, a system-on-chip (SoC) can be configured to receive a request from a master agent in a fabric coupled to the master agent, send a show command grant to the master agent responsive to selection of the request by the fabric, receive a command portion of a transaction corresponding to the request in the fabric and determine a target agent to receive the transaction based on the command portion, and thereafter send a transaction grant to the master agent for the transaction. Other embodiments are described and claimed.
