摘要：Combined indication signals of data block transfers are generated by a devicewhich reduces the number of interrupts to a host processor. The reduction in the numberof interrupts enhances host system performance during data block transfers. Anembodiment of the device may be a network adapter comprising network interface logicfor transferring a data frame between a network and a buffer memory and host interfacelogic for transferring a data frame between a buffer memory and a host system. Thenetwork adapter further includes threshold logic for generating an early receive

indication signal when a portion of the data frame is received. Indication combination logicdelays the generation of a transfer complete interrupt to slightly before the expectedoccurrence of the early receive indication. The host processor is able to service both thetransfer complete indication and the early receive indication in a single interrupt serviceroutine caused by the transfer complete indication.
