Abstract: A method includes inter-chip data communications between a power-managed integrated circuit (IC) and a peer IC. The peer IC generates a data frame and prepends a discardable preamble of a predefined size to a payload of the data frame. The predefined size is a size not less than a size of data discarded by the power-managed IC upon the power-managed IC receiving a data frame while in a low-power state. The peer IC transmits the data frame to the power-managed IC. The power-managed IC, while in a low-power state, may receive the data frame from the peer IC and in response to receiving the data frame, begin exiting the low-power state. The power-managed IC, while exiting the low-power state, may discard a portion of the data frame such as for example, some or all of the discardable preamble, without discarding payload.

Abstract: One embodiment of the present invention provides a system that facilitates intelligent inter-processor communication with power optimization. The system comprises a memory, a first router, a second router, a first physical link coupled between the first router and the second router, and a second physical link coupled between the first router and the second router. Furthermore, the system comprises a first communication bus implemented on the first physical link, as well as a second communication bus implemented on the second physical link. Note that the second communication bus provides lower power consumption and lower bandwidth than the first communication bus. During operation, the system receives a packet at the first router, wherein the packet is destined for the second router. Next, the system selects either the first communication bus or the second communication bus over which to route the packet. Finally, the system routes the packet according to the selection.

Abstract: Adaptive data collection practices in a multi-processor device. The device may include a first processor and a second processor. The first processor may operate in any of a plurality of power states. The first processor may indicate to the second processor when it transitions to a different power state. The second processor may collect information relating to its operation. The second processor may collect the information according to different information collecting modes depending on in which power state the first processor is operating. Less information may be collected in an information collecting mode corresponding to a lower power state of the first processor than in an information collecting mode corresponding to a higher power state of the first processor.
