ABSTRACT:
A communications adapter receives and transmits simultaneously packet and/or isochronous data between two interfaces; a network and a host bus system. The adapter stores the isochronous and packet data in receive and transmit queues configured in a FDDI RAM buffer. A controller manages the transfers of the data into and out of the queues. A local bus interacts with the system to provide descriptors of addresses in the system for transfers of data out of the queues to the system or the network. The controller is programmable to provide a variable threshold for the transfer of data between the queues and the system or the network. A systems interface unit handles the transfer of data to/from the system and allows data to bypass the queues and directly access the system or the network.
