Embodiment

[0034] In this embodiment, an AIF receiving data processing method using a ring buffer and an automatic recovery descriptor uses a host descriptor and initializes a link to form a ring buffer. The present invention adopts an automatic recovery descriptor scheme, which is automatically completed by the QMSS subsystem Recycling of receiving descriptors, the specific implementation includes the following steps:

[0035] S1. Apply for a receiving idle queue, which is referred to as RxFDQ for short, and RxFDQ is used to push the initialized receiving descriptor into the queue; initialization includes the following steps:

[0036] S1.1. First complete the initialization of the Multicore Navigator, as follows:

[0037] The first step is to complete the initialization of the QMSS subsystem, including the initialization of the RAM space of the QMSS, the initialization of the descriptor memory, the initialization of the QMSS related registers, etc.;

[0038] The second step is to compl...

Abstract

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 solved; and the problem that the receiving descriptor needs to be actively recovered by another thread or in an interrupt function is solved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and more specifically, relates to an AIF receiving data processing method using a ring buffer and an automatic recovery descriptor. Background technique [0002] With the gradual improvement of people's communication requirements, communication technology has developed rapidly in recent years. After experiencing 2G (2nd Generation, second generation mobile communication) voice communication, 3G (3rd Generation, third generation mobile communication) data and After voice communication, LTE (Long Term Evolution, long-term evolution) has also been widely used in the world, and the continuous innovation of communication technology has stimulated the development and application of more and more complex DSP (Digital Signal Processing, digital signal processor) chips. On the one hand, these DSP chips need to support higher baseband signal processing rates, and on the other hand, the...
