Abstract:
Des systemes de multiprocesseurs de l'art anterieur utilisent soit un seul ensemble de ressources communes qui sont partagees par tous les processeurs, soit une pluralite de ressources, chacune d'elles etant reservee a un processeur particulier. Dans cette seconde situation, des liaisons d'intercommunication en serie necessitant a la fois la participation des processeurs de transmission et de reception sont utilisees pour transmettre des donnees entre les processeurs. Le systeme d'interconnexion de processeurs en question etablit la connexion de n processeurs independants entre eux (209-1 a 209-n), chacun d'eux etant associe a une pluralite de ressources (205-ia 207-i) lesquelles ressources sont connectees au processeur par un bus local (214-1 a 214-n), de telle sorte que tout processeur du systeme ait acces direct a toute ressource du systeme meme si une telle ressource est associee a un autre processeur.
Abstract:
Systems, methods, and apparatus for communication over a serial bus in accordance with an I3C protocol are described that enable a non-participating device to cause a master device on an I3C bus transmit a STOP condition that terminates a transaction with a slave device coupled to the I3C bus. A method performed at a master device coupled to a serial bus includes initiating a transaction between the master device and a first slave device, terminating the transaction before completion of the transaction when a second slave device intervenes in the transaction, and servicing the second slave device after terminating the transaction. The transaction may include transmissions of data frames over the serial bus. The second slave device may intervene when it is not a party to the transaction.
Abstract:
Methods and apparatuses relating to circuitry to couple an embedded Universal Serial Bus (eUSB) circuit to a Universal Serial Bus (USB) transceiver interface circuit are described. In one embodiment, an apparatus includes an analog front end circuit to couple to a device; a transceiver interface circuit to couple to a serial bus controller; and an adapter circuit coupled between the analog front end circuit and the transceiver interface circuit to convert between a first protocol of the analog front end circuit and a second, different protocol of the transceiver interface circuit.
Abstract:
An interface adapter to identify a first ready signal from a first link layer-to-physical layer (LL-PHY) interface of a first communication protocol indicating readiness of a physical layer of the first protocol to accept link layer data. The interface adapter generates a second ready signal compatible with a second LL-PHY interface of a second communication protocol to cause link layer data to be sent from a link layer of the second communication protocol according to a predefined delay. A third ready signal is generated compatible with the first LL-PHY interface to indicate to the physical layer of the first communication protocol that the link layer data is to be sent. The interface adapter uses a shift register to cause the link layer data to be passed to the physical layer according to the predefined delay.
Abstract:
System and method to transferably store a system state of an electronic component, the system including a processor and a circuit module. The processor is configured to decompose the system state into a plurality of data vectors, and to map each of the plurality of data vectors to a respective bit marker. The circuit module is removably coupled to the electronic component, the circuit module including a memory and a transceiver. The transceiver is coupled to the memory and to a communication link between the memory and the processor, the transceiver operable to send and to receive data at a rate faster than 640 MBps. Data sent and received by the transceiver comprises bit markers mapped by the processor.
Abstract:
An interconnect switch is provided including switching logic executable to facilitate a Peripheral Component Interconnect Express (PCIe)-based interconnect, and further including a 5 control host embedded in the switch to provide one or more enhanced routing capabilities. The control host includes a processor device, memory, and software executable by the processor device to process traffic received at one or more ports of the switch to redirect at least a portion of the traffic to provide the one or more enhanced routing capabilities.
Abstract:
A system and method of conducting precision time management in a universal serial bus system with a retimer. The method includes initiating, from the retimer, a link delay management request on an upstream-facing port of the retimer. The method further includes receiving, at a downstream-facing port of the retimer, a link delay management request and responding to the request received on the downstream-facing port.
Abstract:
Communication bus enables devices to communicate and exchange information and control signals. There is a growing concern over the security of such types of buses. Since any device can transmit any message, and device on the bus which can be compromised poses a threat for the bus. Described is a system to authenticate the source of messages from various devices on a communication bus.
