Summary:The invention discloses an AIF receiving data processing method using an annular Buffer and an automatic recovery descriptor. The method comprises the following steps of S1, applying for a receiving idle queue RxFDQ, and pressing an initialized receiving descriptor into the queue; S2, configuring receiving Flow, and configuring a destination queue in the receiving Flow as the receiving idle queue;S3, after the receiving is finished, pressing received packets into the destination queue according to configuration of the receiving Flow, when the receiving Flow is configured, specifying the destination queue as the receiving idle queue, after receiving PKTDMA receives one packet, automatically pressing a descriptor corresponding to the packet into the tail of the receiving idle queue, and after N data packets are received and the annular Buffer is filled up, automatically using the first descriptor. The problem of data storage position disorder after data loss of the receiving PKTDMA dueto bus congestion can be s
