摘要:
A physical layer interface for a switch. The physical layer interface includes an auto-negotiation circuit, a transceiver, and a serial interface. The auto-negotiation circuit is configured to negotiate a first data transmission rate with a network client. The transceiver is configured to communicate with the network client at the data transmission rate. The serializer interface is configured to communicate with a media access controller (MAC) at a second data transmission rate that is different than the first data transmission rate.

A physical layer interface including an auto-negotiation circuit configured to negotiate a first data transmission rate with a network client; a transceiver configured to communicate with the network client at the first data transmission rate; and a serializer interface configured to communicate with a media access controller at a second data transmission rate that is different than the first data transmission rate. The serializer interface includes a transmitter configured to replicate data received from the network client in response to the first data transmission rate being lower than the second data transmission rate.

A self-reparable semiconductor includes M functional units each including N sub-functional units. Each of the M functional units performs the same function. First ones of the N sub-functional units communicate with second ones of the N sub-functional units over a signal path that passes through third ones of the N sub-functional units. P spare sub-functional units are functionally interchangeable with P of the N sub-functional units. M, N and P are integers greater than one. Switching devices selectively replace at least one of the N sub-functional units of at least one of the M functional units with at least one of the P spare sub-functional units. Corresponding ones of the N sub-functional units of the M functional units perform the same function. The N sub-functional units within each of the M functional units perform different functions.

An integrated circuit comprises a physical layer interface that is implemented by the integrated circuit, that is associated with a network device, and that communicates with an external device via a medium. A first serializer interface implemented by the integrated circuit communicates with the physical layer interface and with a second serializer interface associated with a medium access controller. The first serializer interface communicates with the second serializer interface at a predetermined data transmission rate that is independent of a negotiated transmission rate between the network device and the external device.

A switch includes a first IC and a second IC. The first IC includes a first set of (N+1) serializer/deserializer (SERDES) modules communicating with a first set of (N+1) SERDES modules of a switch IC; a first set of N SERDES modules communicating with a first set of N ports; and a first set of N multiplexer modules communicating with (i) the first set of N SERDES modules and (ii) the first set of (N+1) SERDES modules of the first IC. The second IC includes a second set of (N+1) SERDES modules communicating with a second set of (N+1) SERDES modules of the switch IC; a second set of N SERDES modules communicating with a second set of N ports; and a second set of N multiplexer modules communicating with (i) the second set of N SERDES modules and (ii) the second set of (N+1) SERDES modules of the second IC.
摘要:
A self-reparable semiconductor including a graphics processing unit includes a first pixel processor that performs a first function and a first spare pixel processor. The first and first spare pixel processors are functionally interchangeable. Switching devices communicate with the first and first spare pixel processors and replace the first pixel processor with the first spare pixel processor when the first pixel processor is inoperable. A controller identifies at least one inoperable pixel processor and generates configuration data for configuring the switching devices to replace the inoperable pixel processor. Memory that is located on the self-reparable semiconductor stores the configuration data for the switching devices. A second pixel processor is functionally interchangeable with the first and first spare pixel processors. The first spare pixel processor is located one of between the first and second pixel processors or adjacent to one of the first or the second pixel processors.

摘要:
A self-reparable semiconductor includes multiple functional units that perform the same function and that include sub-functional units. The semiconductor includes one or more full or partial spare functional units that are integrated into the semiconductor. If a defect in a sub-functional unit is detected, then that sub-functional unit is switched out and replaced with a sub-functional unit in the full or partial spare functional unit. The reconfiguration is realized with switching devices that are associated with the sub-functional units. Defective functional or sub-functional units can be detected after assembly, during power up, periodically during operation, and/or manually.

A network device includes a first integrated circuit and a second integrated circuit. The first integrated circuit includes a media access controller and a first serializer interface in communication with the media access controller. The second integrated circuit includes a physical layer interface in communication with an external device. The second integrated circuit also includes a second serializer interface in communication with the physical layer interface and the first serializer interface. The second serializer interface communicates with the first serializer interface at a predetermined data transmission rate regardless of a negotiated transmission rate between the network device and the external device.
