摘要： A network adapter with an interrupt generation circuit to minimize the number of host computer system interrupts needed to notify the host computer system that the network adapter has consumed one or more host memory buffers. The interrupt generation circuit issues an interrupt to the host computer system when the host computer system has entered both a transmit sleep state and a receive sleep state, and the network adapter has consumed a host memory buffer not processed by the host computer system. When the host computer system has no work to do with respect to transmit buffers in the host computer memory, it enters a transmit sleep state and indicates to the network adapter the last transmit buffer it processed. When the host computer system has no work to do with respect to receive buffers in the host computer memory, it enters a receive sleep state and indicates to the network adapter the last receive buffer it processed. If subsequent to both these indications, the network adapter consumes a host memory buffer that the host computer system has not processed, the interrupt generation circuit issues an interrupt to the host computer system. The network adapter further includes means for the host computer system to notify the network adapter that the host computer has produced multiple host memory buffers for the network adapter to consume.
摘要翻译：具有中断产生电路的网络适配器，以最小化通知主机系统网络适配器已消耗一个或多个主机内存缓冲区所需的主机计算机系统中断次数。当主计算机系统进入发送休眠状态和接收休眠状态时，中断产生电路向主计算机系统发出中断，并且网络适配器已经消耗了未被主机系统处理的主机存储器缓冲器。当主计算机系统对于主计算机存储器中的发送缓冲器没有任何工作时，它进入发送休眠状态，并向网络适配器指示其处理的最后发送缓冲器。当主计算机系统与主计算机存储器中的接收缓冲区无关的工作时，它进入接收休眠状态，并向网络适配器指示其处理的最后一个接收缓冲器。如果在这两个指示之后，网络适配器消耗主机系统尚未处理的主机内存缓冲区，则中断产生电路向主机系统发出中断。网络适配器还包括用于主计算机系统通知网络适配器主机计算机已经产生用于网络适配器消耗的多个主机存储器缓冲器的装置。

摘要： A network adapter with high throughput data transfer circuit to optimize network data transfers, with host receive ring resource monitoring and reporting is disclosed. Time critical network data is transferred between the network adapter and the host computer system by means of a high throughput data transfer circuit. The high throughput data transfer circuit is designed to provide throughput equal to the bandwidth of a high speed local area network such as the Fiber Distributed Data Interconnect. The high throughput data transfer circuit will inform the local intelligence of the network adapter if the network adapter has used up all host computer system memory allocated for storing data received from the network. Adapter management data is transferred between the network adapter and the host computer system local area network through a lower throughput data transfer circuit.
