Abstract:
An interface in which packets are received having a plurality of variant formats, and transferred to a host system, comprising:a first port on which incoming data is received at a data transfer rate; a buffer, coupled to the first port, storing received packets; a second port, coupled with the buffer, through which transfer of packets to the host is executed; a packet filter, coupled to the first port, which identifies packets being stored in the buffer having one of the plurality of variant formats; first logic coupled with the buffer and the second port, to transfer packets from the buffer to the second port; and second logic coupled with the buffer, and responsive to the packet filter to read and process data in the identified packets from the buffer, and to produce a data value dependent on contents of the packet prior to transfer of the identified packets to the second port by the first logic.
