摘要： A packet processing method and device are provided, to save CPU resources consumed by parsing a packet. The method includes: parsing, by an intelligent network interface card, a received first packet to obtain an identifier of the first packet; updating, by the intelligent network interface card, a control field of a first memory buffer based on the identifier of the first packet; storing, by the intelligent network interface card, a payload of the first packet or a packet header and a payload of the first packet into the first address space through DMA based on an aggregation position of the first packet; aggregating, by a host, the first address information and at least one piece of second address information based on an updated control field in the first mbuf; and reading, by a virtual machine, address information, to obtain data in an address space indicated by the address information.

摘要： Technologies for low-latency data streaming include a computing device having a processor that includes a producer and a consumer. The producer generates a data item, and in a local buffer producer mode adds the data item to a local buffer, and in a remote buffer producer mode adds the data item to a remote buffer. When the local buffer is full, the producer switches to the remote buffer producer mode, and when the remote buffer is below a predetermined low threshold, the producer switches to the local buffer producer mode. The consumer reads the data item from the local buffer while operating in a local buffer consumer mode and reads the data item from the remote buffer while operating in a remote buffer consumer mode. When the local buffer is above a predetermined high threshold, the consumer may switch to a catch-up operating mode. Other embodiments are described and claimed.

摘要： An apparatus and method for queuing data to a memory buffer. The method includes selecting a queue from a plurality of queues; receiving a token of data from the selected queue and requesting, by a queue module, addresses and pointers from a buffer manager for addresses allocated by the buffer manager for storing the token of data. Subsequently, a memory list is accessed by the buffer manager and addresses and pointers are generated to allocated addresses in the memory list which comprises a plurality of linked memory lists for additional address allocation. The method further includes writing into the accessed memory list the pointers for the allocated address where the pointers link together allocated addresses; and migrating to other memory lists for additional address allocations upon receipt of subsequent tokens of data from the queue; and generating additional pointers linking together the allocated addresses in the other memory lists.

摘要： The disclosure describes a data enqueuing method. The method may include: receiving a to-be-enqueued data packet, dividing the data packet into several slices to obtain slice information of the slices, and marking a tail slice of the data packet with a tail slice identifier; enqueuing corresponding slice information according to an order of the slices in the data packet, and in a process of enqueuing the corresponding slice information, if a slice is marked with the tail slice identifier, determining that the slice is the tail slice of the data packet, and generating a first-type node; and determining whether a target queue is empty, and if the target queue is empty, writing slice information of the tail slice into the target queue, and updating a head pointer of a queue head list according to the first-type node.

摘要： A first memory device stores (i) a head part of a FIFO queue structured as a linked list (LL) of LL elements arranged in an order in which the LL elements were added to the FIFO queue and (ii) a tail part of the FIFO queue. A second memory device stores a middle part of the FIFO queue, the middle part comprising a LL elements following, in an order, the head part and preceding, in the order, the tail part. A queue controller retrieves LL elements in the head part from the first memory device, moves LL elements in the middle part from the second memory device to the head part in the first memory device prior to the head part becoming empty, and updates LL parameters corresponding to the moved LL elements to indicate storage of the moved LL elements changing from the second memory device to the first memory device.

摘要： A method for displaying an animation by a display chip of an electronic device, which includes a non-volatile memory and a random-access memory. The display chip includes a video output register and a display register. The method includes a first static programming phase including configuring the video output register; writing n images in the memory, n being an integer higher than or equal to two; writing into the memory of a plurality of nodes, such that each node includes the address in the memory of at least one portion of an image, as well as the address of the following node in the memory, the last node including the address in the random-access memory of the first node; and configuring the display register. The method also includes a second phase in which the n images are read by the display chip by the display register, to display the animation.

摘要： A node device (1A) receives a second ACK list in communication with an adjacent node (1B) and updates a first ACK list and a first summary vector on the basis of the second ACK list. The first summary vector, which indicates messages stored in a message buffer of the node device (1A), is transmitted to the adjacent node (1B) prior to transmission of the messages in the communication with the adjacent node (1B). The first ACK list indicates ACK messages recognized by the node device (1A). The second ACK list indicates ACK messages recognized by the adjacent node (1B). Each ACK message represents a message of arrival at an ultimate destination node via a DTN (100). In this way, for example, a copy having the same content as a message having arrived at an ultimate destination node can be prevented from being scattered in the Disruption Tolerant Network (DTN).
