Embodiment Construction

[0029]The present invention proposes to provide a simplified 1553B system interface, the circuit has a complete RT function of the 1553B bus, and its power-on automatic configuration module realizes the setting of the RT working state by setting its configuration register, and the multi-clock selection module also passes The Set Register block determines the operating frequency of the circuit. The BC->RT message received from A or B transceiver first enters the channel selection module through the Manchester II decoder and enters the RT protocol logic. The RT module parses the message command to obtain the address information of the corresponding subsystem, and passes the DMA The way to transfer data to the subsystem. During this period, if the burst mode is used, the circuit will temporarily store the received data words in the FIFO first, and after the last data word is received and confirmed to be valid, the data in the FIFO will be continuously moved to the corresponding s...

Abstract

The invention relates to a simplified system interface 1553B remote terminal circuit. As the original 1553B protocol processor structure is not changed, only the input control logic is added, which can make the circuit complete the configuration without the initialization of the microprocessor, and save a microprocessor and related supporting circuits for the system, thus greatly simplifying the design complexity of the 1553B terminal data acquisition system. A burst message processing mode is provided, the 32*16bit FIFO is used to temporarily buffer the data word from BC, and after receivingthe last data word and confirming the correct reception status, the transfer of data word from FIFO to the corresponding subsystem memory can be realized, which can reduce the number of DMA handshakeswith this circuit and subsystem.

Description

technical field [0001] The invention relates to a simplified system interface 1553B remote terminal circuit, which belongs to the field of 1553B remote terminals. Background technique [0002] The 1553B bus controller is the "central nerve" of military electronic systems. In the past 50 years, the 1553B bus has realized the information sharing and transmission of sensors and other electronic equipment with its advantages of high reliability and determinism, and has been widely used It is used in military fields such as aviation, aerospace, weapons and ships, and has become a typical representative of combined military electronic systems. At present, the most widely used is the BU-65170 series circuit produced by DDC Company. Every time the circuit is powered on, the microprocessor needs to initialize its configuration registers and memory, which increases the design complexity, size and power consumption of the system for simple terminal systems that only need data collecti...
