摘要： Programmable hardware devices are re-programmed without system downtime. To re-program the device, the device is quiesced, state associated with the device is saved, updates are loaded, the state is restored and operations are resumed, all transparent to the system, except for a possible delay in the system.

摘要： Processing within a device is controlled in order to avoid a deadlock situation. A local request engine of the device determines prior to making a request whether the port of the device that is to service the request is making forward progress in processing other requests. If forward progress is being made, then the request is forwarded to the port. Otherwise, the request is held. This avoids a deadlock situation and allows the device to remain operative even in partial recovery situations.

摘要： A task obtained by a communications processor is decomposed into one or more requests that form a request group. The requests of the request group are sent to main memory and responses to those requests are expected. There may be requests for a plurality of request groups being processed concurrently. However, responses to the request groups are to be returned to the communications processor in the order in which the request groups were sent from the communications processor. To ensure this ordering, dependencies between the request groups are tracked by hardware coupled to the communications processor.
摘要翻译：由通信处理器获得的任务被分解成形成请求组的一个或多个请求。请求组的请求被发送到主存储器，并且期望对这些请求的响应。可能需要同时处理多个请求组的请求。但是，请求组的响应将按照从通信处理器发送请求组的顺序返回给通信处理器。为了确保这种排序，请求组之间的依赖关系由耦合到通信处理器的硬件进行跟踪。

摘要： The utilization of a controlled buffer and tags associated with read requests and the transmission of data in response to these requests, along with the transmitted tag information, is used to avoid a read-modify-write operations occurring in a communications adapters whose function it is to assemble various pluralities of data blocks, each with a varying amount of information, into single data packets for transmission from the adapter's memory. The presence of error correction capabilities associated with the adapter's memory would otherwise require the utilization of the read-modify-write operation which is bandwidth limiting.

摘要： In order to solve the problem of the detection of the arrival of duplicate data packets in an interconnected, multinode data processing system, each data packet is provided with a field of r bits that are randomly generated for each data packet. However, one of the packets is provided with a field that is computed from the other randomly generated field entries in a checksum computation which yields a selected nonzero checksum value. A running checksum at the receiver is used to determine whether or not, after the receipt of the specified number, k, of data packets, a duplicate packet has been received.
