Abstract: A data transmission acceleration method and related apparatuses are disclosed. A sanding node transmits a plurality of data packets to a receiving node at an initial transmission rate. Each data packet carries a random sequence number and a rolling sequence number. The random sequence number identifies a data part of the data packet, and the rolling sequence number indicates a transmission sequence of the data packet. The sending node receives a packet loss feedback from the receiving node. The packet loss feedback is generated after the receiving node detects a packet loss event according to a rolling sequence number of a received data packet. The sending node determines a random sequence number of a lost data packet based on the received packet loss feedback. The sending node retransmits a data packet corresponding to the determined random sequence number. The retransmitted data packet carries a new rolling sequence number.

Abstract: The present invention provides a conversion circuit including: an inputting unit, a DAC connected to the inputting unit, an ADC connected to an output end of the DAC, and a comparing unit connected to an output end of the ADC. The comparing unit compares a test code set output by the ADC with a second standard test code set, and if the comparison result is in a preset error range, notify a test data collecting unit; otherwise, output the comparison result to a correcting unit. The correcting unit obtains a complementary code set according to the comparison result, and output the complementary code set to the inputting unit, so that the inputting unit updates the standard test code set according to the complementary code set and obtains the updated first standard test code set. The test data collecting unit obtains a voltage value of an input end of the ADC.
