摘要： A communication function between ports on a node that does not require a common time base to be distributed across the network is disclosed. A data stream received over a first port is placed on an interlace between nodes using the time base of the first port; a second port samples the data stream on the interface and timestamps it using the time base of the second port. The data stream is timestamped by the second port and packetized before transmitted to the second node to another bridge or device. Alternatively, the first port extracts a time stamp from the data stream and calculates an offset using a cycle timer value from the bus connected to the first port. The offset is added to the cycle timer value on the bus connected to the second port and used to timestamp the data stream.

摘要： A method and apparatus relating to the behavior of border nodes within a high performance serial bus system is disclosed. A method is disclosed for determining a path to a senior border during the Self-ID process in a full-duplex communications system having at least one border node comprising the acts of: marking the border node as the senior border; determining whether the border node has received a Self-ID packet that does not contain a Speed Code on a parent beta port of the border node; marking the port on said border node as the path to the senior border node if the border node has received a Self-ID packet that does not contain a Speed Code on a parent beta port of the border node; and canceling the border node's own status as a senior border node.

摘要： A method and apparatus of improving serial bus efficiency. Improvement of bus efficiency through the reduction of enforced subaction gaps can be accomplished by attaching an explicit end of subaction (EOS) token to packets that are the last packet of a subaction. The EOS should be selected to be an encoding that is not easily confused with any encoding used for normal data encoding. The presence of the EOS token permits arbitration to begin without waiting for a subaction gap after the EOS token is seen on the bus. Additionally, it permits fly by concatenation with packets containing an EOS token. In some cases multiple concatenations are possible. Because the EOS token is independent of subaction type, this technique expands readily as new subactions are developed. Employing the features overall bus efficiency can be increased.

摘要： To securely factory activate a mobile device according to authorized records, factory activation server generates and sends a signed factory activation record including a signed factory activation ticket. Signed factory activation record and ticket are cryptographically signed using factory private key stored in factory activation server. Factory private key is different from customer private key stored in the activation server that provides activation tickets for customer activation. If factory activation record is valid, application processor (AP) included in the device performs factory activation of the device which includes AP activating to allow for factory testing and rebooting at a predetermined reboot time. Wireless communication processor (BB) included in the device verifies the factory activation ticket and if valid, BB performs factory activation including: BB registering to a cellular telephone communications network for factory testing, and unregistering from the network after a predetermined unregistering time. Other embodiments are also described.

摘要： Securely installing and booting software of a device to run OS authorized according to a ticket that is validated by a nonce generated by application processor (AP) in booted OS stage prior to entering a restore mode is described. AP in booted OS stage generates a pre-flight nonce that is stored in a trusted location (effaceable storage). AP in booted OS stage performs one-way hash of pre-flight nonce and sends the hashed pre-flight nonce to ticket authorization server. AP enters restore mode. AP in first stage bootloader receives a ticket from the ticket authorization server including a signed copy of the hashed pre-flight nonce. AP in first stage bootloader validates the signed ticket by comparing one-way hash of the pre-flight nonce stored in the trusted location and the hashed nonce in the signed ticket. Pre-flight nonce expires after timeout period and upon reboot of AP. Other embodiments are also described.

摘要： A method for determining and communicating the existence of a hybrid bus is disclosed. The method determines whether a connected node is a border node and forwards isochronous and asynchronous requests if the node is not a border node. If the node is a border node, a Border low request is issued if there are no asynchronous requests to forward. If there are asynchronous requests to forward then these asynchronous requests are forwarded. A Border low request is issued if there are no isochronous requests to forward; otherwise any isochronous requests to be forwarded are forwarded.

摘要： A method and apparatus for reclaiming bus bandwidth on a full duplex bus. A source node sends a primary packet toward a destination node along a full duplex bus. If the destination node identifies an inability to accept the primary packet, it sends a NAK in the opposite direction along the full duplex bus towards the source node. Upon receiving the NAK, the source node aborts packet transmission of the primary packet which by virtue of the NAK has been identified as futile. Accordingly, the bandwidth, which would have otherwise have been used for the futile packet transmission, can be reclaimed and used for some other purpose.
摘要翻译： 一种用于在全双工总线上回收总线带宽的方法和装置。 源节点沿着全双工总线向目的地节点发送主分组。 如果目标节点识别出不能接受主分组，则沿着全双工总线向相反方向向源节点发送NAK。 在接收到NAK时，源节点中止主分组的分组传输，由于NAK被识别为无效。 因此，否则将用于无效分组传输的带宽可以被回收并用于某种其他目的。
