Abstract: A system for consistently implementing reset and power management of IP agents on a System on a Chip (SoC). When IP agents undergo a reset, an individual negotiation takes placed between an interconnect and each IP agent over a link. Each IP agent can emerge from reset at its own time schedule, independently of the timing of the other IP agents. The interconnect may be configured as a proxy for any IP agent that is inoperable, including prior to reset, when in a power-down mode, or malfunctioning.

Abstract: Optimizing transaction traffic on a System on a Chip (SoC) by using procedures such as expanding transactions and consolidating responses at nodes of an interconnect fabric for broadcasts, multi-casts, any-casts, source based routing type transactions, intra-streaming two or more transactions over a stream defined by a paired virtual channel-transaction class, trunking physical resources sharing common logical identifier, and using hashing to select among multiple physical resources sharing a common logical identifier.

Abstract: Arbitrating among portions of multiple transactions and transmitting a winning portion over one of a multiplicity of virtual channels associated with an interconnect on a clock cycle-by-clock cycle basis. By repeatedly performing the above each clock cycle, winning portions are interleaved and transmitted over the multiplicity of virtual channels over multiple clock cycles respectively.

Abstract: In one embodiment, a controller is configured to receive a flow control packet from a link partner on a communication medium. The flow control packet includes a channel indication that indicates one or more channels. The controller is configured to inhibit transmission of packets from at least one channel specified by the channel indication and to permit transmission of packets from channels not specified in the channel indication. The controller may also be configured to transmit the flow control packet in response to detecting a need to flow control one or more channels from the link partner.

Abstract: In one embodiment, a system comprises a communication medium; a first controller coupled to the communication medium; and a second controller coupled to the communication medium. The first controller is configured to interrupt transmission of a packet on the communication medium to the second controller subsequent to transmission of a first portion of the packet. The first controller is configured to transmit at least one control symbol on the communication medium in response to interrupting transmission of the packet, and wherein the first controller is configured to continue transmission of the packet with a second portion of the packet. The controller(s) may include, in some embodiments, a media access controller and a physical coding sublayer.

Abstract: A distributed arbitration scheme includes arbiters with each agent. The arbiters receive request signals indicating which agents are arbitrating for the bus. Additionally, the agent currently using the bus broadcasts an agent identifier assigned to that agent. The arbiters receive the agent identifier and use the agent identifier as an indication of the winner of the preceding arbitration. Accordingly, the arbiters determine if the corresponding agent wins the arbitration, but may not attempt to calculate which other agent wins the arbitration. In one embodiment, the arbiter maintains a priority state indicative of which of the other agents are higher priority than the corresponding agent and which of the other agents are lower priority. In one implementation, the bus may be a split transaction bus and thus each requesting agent may include an address arbiter and each responding agent may include a data arbiter.
