Embodiment Construction
[0028] Such as figure 1 Shown is a structural block diagram of the 1553B bus IP core of the present invention. The 1553B bus IP core includes a BC module, an RT module, a BM module, an encoder, a decoder, a message parsing module, a storage module, an interrupt module, a time stamp module, a self-test module, a global register, and a bus arbitration module.
[0029]The BC module is the initiator of 1553B bus messages, including BC message control submodule, BC memory read and write control submodule, and internal buffer area; the BC module reads the configuration information in the global register, and reads the BC from the external memory through the bus arbitration module The message control block and BC data control block extract the 1553B bus message and send it to the transceiver through encoder A or encoder B; the messages on the 1553B bus are transmitted to the message analysis module through the transceiver, decoder A or decoder B , the message parsing module transmit...

The invention discloses a linked list-based full-function 1553B bus IP (Internet Protocol) core, which comprises a BC module, an RT module, a BM module, an encoder, a decoder, a message parsing module, a memory module, an interruption module, a time scale module, a self-detection module, a global register and a bus arbitration module. Compared with the conventional 1533B bus IP core, data of the BC module, the RT module and the BM module is managed in a linked list mode, a next address is automatically acquired through a pointer, addressing calculation is performed without occupying resource, the data is continuously stored in a memory space, the storage resource is not wasted, the utilization of the resource is guaranteed to the greatest extent, conciseness and miniaturization of the system are facilitated, and the system performance is greatly improved.
Description
technical field [0001] The invention belongs to the field of avionics bus technology, in particular to a full-function 1553B bus IP core based on linked list. Background technique [0002] MIL-STD-1553B defines a digital time division command / response type multiplexed data bus. The bus has the characteristics of definite transmission delay, reliable transmission capacity, and strong fault tolerance, and has been widely used abroad. China released the corresponding national military standard GJB289A-97 in 1997. After years of development, the current 1553B bus technology has been extended to aviation, aerospace, ships, missiles and other fields, and achieved good results. Judging from the development trend and practical application of my country's current electronic bus technology, in the next 5-10 years, the 1553B bus will still occupy a dominant position in the military electronic bus. [0003] The key part of the 1553B bus is the protocol processor. At present, most dom...
