Abstract

The invention relates to an avionic ASM (automatic storage management) protocol control method and a controller thereof. The method comprises a sending step, wherein the sending step comprises the following procedures: 1) acquiring control attributes of a message queue, wherein the control attributes of the message comprise message ID, message type, count period, queue base address (QueueBase), queue length (QueueLen), head pointer (Head), maximum message length (MsgMaxLen), tail pointer (Tail), destination address (DID) and count of sent segmentations (Send Cnt); and the message type refers to an emergency message, a period message or an event message; 2) selecting the message queue to be sent in accordance with the control attributes of the message queue; 3) finding out the content of the message based on the message queue selected in procedure 2), and segmenting; and 4) encapsulating the message segmentations obtained in procedure 3), submitting, and sending. Thus, the invention provides an avionic ASM protocol controller and control method, which has the advantages of high transmission efficiency, low communication expense and definitive scheduling.

Description

technical field [0001] The invention belongs to the field of computer control, in particular to an avionics ASM protocol controller and a control method. Background technique [0002] The new generation of military aircraft avionics system uses Fiber Channel FC as the airborne unified network, and the transmission rate of a single node is 2Gb / s, which is used to transmit information such as messages, data, and images. ASM is based on the high-level communication protocol of FC network. It has the characteristics of determinism, security and low delay. It is mainly used in the backbone communication network of avionics system. The ASM communication protocol is generally processed by host software, which occupies a large amount of CPU processing resources and has a large protocol processing overhead. The processing time of the communication protocol far exceeds the transmission time of the data frame. The efficiency of the communication interface is low and the transmission d...
