摘要： Techniques and mechanisms for exchanging single-ended communications with a protocol stack of an integrated circuit package. In an embodiment, an integrated circuit (IC) chip includes a protocol stack comprising a transaction layer which performs operations compatible with a Peripheral Component Interconnect Express™ (PCIe™) specification. Transaction layer packets, exchanged between the transaction layer and a link layer of the protocol stack, are compatible with a PCIe™ format. In another embodiment, a physical layer of the protocol stack is to couple the IC chip to another IC chip for an exchange of the transaction layer packets via single-ended communications. A packaged device includes both of the IC chips.

摘要： In one embodiment, the present invention includes method for entering a credit initialization state of an agent state machine of an agent coupled to a fabric to initialize credits in a transaction credit tracker of the fabric. This tracker tracks credits for transaction queues of a first channel of the agent for a given transaction type. The agent may then assert a credit initialization signal to cause credits to be stored in the transaction credit tracker corresponding to the number of the transaction queues of the first channel of the agent for the first transaction type. Other embodiments are described and claimed.
