Abstract
Description
Technical Field
[0001] The present disclosure relates to a data transceiving method and a data transceiving device, and more particularly to a data transceiving method and a data transceiving device that assist in transmitting general priority data through a high priority request block. Background Art
[0002] In terms of data transmission, it is usually hoped that the USB Request Block (URB) can carry the maximum amount of data. Therefore, data is aggregated to facilitate the request block to send data. However, this will result in high-priority data not being able to obtain low latency.
[0003] On the other hand, in order to improve the transmission efficiency of high-priority data and reduce transmission delay, if high-priority data is encountered, the request block will transmit the data immediately. However, the above operation will cause the general priority data following the high-priority data to wait, thereby causing a delay in the general priority data. Summary of the Invention
[0004] In view of the deficiencies in the prior art, one of the objectives of the present disclosure is (but not limited to) to provide a data transceiving method and a data transceiving device to improve the deficiencies in the prior art.
[0005] In some embodiments, the data sending and receiving method includes the following steps: sending and receiving multiple general priority data through a first request block; sending and receiving multiple high priority data through a second request block; and if the first request block cannot send and receive part of the multiple general priority data, sending and receiving part of the multiple general priority data through the second request block.
[0006] In some embodiments, the data transceiver device includes a memory and a processor. The memory is configured to store at least one instruction. The processor is configured to read the at least one instruction and execute the following steps: transmitting and receiving a plurality of general priority data using a first request block; transmitting and receiving a plurality of high priority data using a second request block; and transmitting and receiving a portion of the plurality of general priority data using the second request block if the first request block cannot transmit or receive a portion of the plurality of general priority data.
[0007] The technical means embodied in the embodiments of the present disclosure can improve at least one of the shortcomings of the prior art. The data transceiver method and data transceiver device disclosed herein assist in the transmission of general priority data through high-priority request blocks, thereby improving the transmission efficiency of high-priority and general priority data and reducing transmission delay.

Thus, a first element herein could also be referred to as a second element without departing from the spirit of the present disclosure. For ease of understanding, similar elements in the drawings will be designated with the same reference numerals.
[0036] In order to improve the problem of delay in general priority data caused by prioritizing the transmission of high priority data, the present disclosure proposes a data transceiver method and a data transceiver device, which are described in detail below.
[0037] Figure 1 The following is a schematic diagram of a data transceiver device 100 according to some embodiments of the present disclosure. As shown in the figure, the data transceiver device 100 includes a processor 110 and a memory 120. The memory 120 is used to store at least one instruction. The processor 110 is used to read at least one instruction to perform data transmission. To make the operation of the data transceiver device 100 easier to understand, please refer to Figure 2 , Figure 2 FIG. 2 is a flow chart of a data transceiving method 200 according to some embodiments of the present disclosure.
[0038] In step 210, a plurality of normal priority data are sent and received via a first request block. In step 220, a plurality of high priority data are sent and received via a second request block. For example, the present disclosure can receive and send a plurality of normal priority data via a first request block (USB Request Block, URB). Alternatively, the present disclosure can receive and send a plurality of high priority data via a second request block (URB).
[0039] In step 230, if the first request block is unable to transmit or receive partial data of the plurality of normal priority data, the second request block is used to transmit or receive partial data of the plurality of normal priority data. For example, if the first request block (URB) is full and unable to receive or transmit partial data of the plurality of normal priority data, the second request block (URB) can be used to assist in receiving and transmitting partial data of the plurality of normal priority data, thereby reducing transmission delay of the normal priority data.
[0040] Figure 3A The following is a schematic diagram illustrating the operation of a data transceiver 100 according to some embodiments of the present disclosure. For ease of understanding, general priority data is represented by general passengers 311, 312, and 313, high priority data is represented by high priority passengers 321 and 322, the first request block is represented by the first bus URB1, and the second request block is represented by the second bus URB2.
[0041] First, general passengers 311, 312, and 313 and high-priority passengers 321 and 322 are arranged in the same queue. Then, general passengers 311 and 312 are assigned to the first bus URB1 according to their order of arrangement within the queue, and high-priority passengers 321 and 322 are assigned to the second bus URB2 according to their order of arrangement within the queue. However, since the first bus URB1 is full, general passenger 313 can no longer board the first bus URB1. In this case, general passenger 313 can be assigned to the second bus URB2 within the queue, which will carry general passenger 313. As described above, general priority data, the first request block, and the second request block are represented by general passenger 313, the first bus URB1, and the second bus URB2, respectively. As can be seen from the above embodiment, the present disclosure can utilize the second request block URB2 to assist in receiving and transmitting general priority data 313 when the first request block URB1 is unable to receive and transmit general priority data 313, thereby reducing the transmission delay of general priority data 313. On the other hand, the present disclosure uses the second request block URB2 to assist in sending and receiving the general priority data 313, and no additional delay is added to the high priority data 321, 322. It should be noted that the packet order of the high priority data packets of the present disclosure will maintain the original high priority order, that is, the high priority data will still be sent in advance and will not be delayed due to the need to wait for transmission (only the existing part can be processed), even if Figure 3A The first request block URB1 and the second request block URB2 can still be interchanged Figure 3A Implement in a corresponding manner.
[0042] Figure 3B The following is a schematic diagram illustrating the operation of a data transceiver 100 according to some embodiments of the present disclosure. For ease of understanding, general priority data is represented by general passengers 411 and 412, high priority data is represented by high priority passenger 421, the first request block is represented by first bus URB1, and the second request block is represented by second bus URB2.
[0043] First, general passengers 411 and 412 are arranged into a first queue Q1. Next, high-priority passenger 421 is arranged into a second queue Q2. After the second bus URB2 carries high-priority passenger 421, if general passengers 411 associated with the first bus URB1 still exist, the general passengers 411 can be assigned from the first queue Q1 to the second bus URB2, which will then carry the general passengers 411. Furthermore, general passenger 412 can be assigned to the first bus URB1. As described above, general priority data, high priority data, the first request block, and the second request block are represented by general passenger 411, high-priority passenger 421, the first bus URB1, and the second bus URB2, respectively. As can be seen from the above embodiment, the present disclosure allows the second request block URB2 to transmit and receive general priority data 411 after the second request block URB2 transmits and receives high-priority data 421, if general priority data 411 associated with the first request block URB1 still exists.
[0044] Figure 4 The following is a schematic diagram illustrating the operation of a data transceiver 100 according to some embodiments of the present disclosure. For ease of understanding, general priority data is represented by general passengers 411, 412, and 413, high priority data is represented by high priority passenger 421, the first request block is represented by first bus URB1, and the second request block is represented by second bus URB2.
[0045] First, regular passengers 411, 412, and 413 are arranged into a first queue Q1. Regular passengers 411 and 412 are then assigned to the first bus URB1 according to their order of arrangement within the first queue Q1. Next, high-priority passenger 421 is arranged into a second queue Q2. High-priority passenger 421 is assigned to the second bus URB2 according to their order of arrangement within the second queue Q2. However, since the first bus URB1 is full, regular passenger 413 cannot board the first bus URB1. In this case, regular passenger 413 is assigned to the second bus URB2 from the first queue Q1, which then carries regular passenger 413. As described above, the general priority data, the first request block, and the second request block are represented by the general passenger 413, the first bus URB1, and the second bus URB2, respectively. From the above embodiment, it can be seen that the present disclosure can assist in receiving and sending the general priority data 413 by the second request block URB2 when the first request block URB1 is unable to receive and send the general priority data 413, so as to reduce the transmission delay of the general priority data.
[0046] Figure 5The flowchart of a data transmission and reception method 500 according to some embodiments of the present disclosure is shown. As shown, in step 510, a data packet is received. Subsequently, in step 520, a determination is made as to whether the data packet is a high-priority data packet. If the data packet is a high-priority data packet, step 530 is executed to insert the high-priority data packet into a high-priority queue. Alternatively, if the data packet is not a high-priority data packet, step 525 is executed to insert a normal-priority data packet into a normal-priority queue.
[0047] Next, in step 540, it is determined whether the high priority queue is not empty. If the high priority queue is not empty, step 550 is executed to dequeue the high priority data packet and prepare the Bulk URB. Alternatively, if the high priority queue is not empty, step 545 is executed to dequeue the normal priority data packet and prepare the Bulk URB.
[0048] Next, in step 560, a determination is made as to whether the request block is full. If the request block is full, step 570 is executed, and the request block sends or receives data packets. If the request block is not full, step 565 is executed to determine whether the normal priority queue is empty. If the normal priority queue is empty, step 570 is executed, and the request block sends or receives data packets. If the normal priority queue is not empty, step 545 is executed to dequeue the normal priority data packet and prepare the Bulk URB. Next, in step 580, when the request block is full or there is no more data to be sent, the request block sends or receives data packets.
[0049] Figure 6 as well as Figure 7 A schematic diagram of data transmission and reception and confirmation signals drawn according to some embodiments of the present disclosure. Figure 6 The schematic diagram of the data transceiving method 200, 500 and the data transceiving device 100 without the present disclosure is shown. As can be seen from the figure, there is a large delay (latency) between data transmission and reception and the confirmation signal ACK, which will cause all data transmission and reception to be delayed. Figure 7 , Figure 7Schematic diagrams of the data transceiving methods 200 and 500 and the data transceiving device 100 according to the present disclosure are shown. As can be seen from the diagrams, there is basically almost no delay between data transmission and reception and the confirmation signal ACK, which will make all data transmission and reception almost delay-free.
