A method of providing switch arbitration for the passing of packets between transmitters and receivers in a switch having a plurality of transmitters and receivers, comprises globally distributing information about buffer contents and packet requests between transmitters and receivers.

Switch arbitration

An interconnect apparatus provides for the buffering of information in respective transaction buffers according to transaction type. An additional buffer is dynamically assignable to one of the transaction buffers where additional capacity is required by that transaction buffer.

Method, system, and apparatus for dynamic buffer space allocation

An Infiniband device can have an input port operable to receive a packet and to forward the packet to an output port of the device for onward transmission toward an ultimate destination of the packet. The input port can also be operable to examine at least a header portion of the packet to determine a transmission validity status of the packet and in the event of a negative transmission validity status being determined, to truncate the packet to remove a data payload from the packet including regenerating a checksum field of the packet on the basis of a truncated size of the packet.

Stumping mechanism

A receiver for digital data is provided. The receiver comprises a ring buffer operable to store received data. The receiver also comprises a write pointer controller for the buffer, operable to control the writing of received data into the buffer, and a read pointer controller for the buffer, operable to control the reading of data from the buffer. The receiver further comprises a pointer adjustment controller operable, in response to a detection of a special data indicator, to control at least one of the write pointer controller and the read pointer controller using forward looking operable to foresee a data location within the buffer corresponding to a future read location of the buffer.

Data transfer

A verification process comprises a verification environment having a hardware development language interface. The verification process also comprises a device under test having a hardware development language interface operable to communicate with the verification environment hardware development language interface, and also having an Infiniband interface. The verification process additionally comprises a remote Infiniband link having an Infiniband interface operable to communicate with the device under test Infiniband interface and also having a socket protocol interface operable to communicate with a further verification process.
