Embodiment Construction

[0017] refer to Figure 1-2 . The DSP-based 1553B bus protocol module of the present invention includes five parts: a 1553B bus interface circuit, a logic synthesis circuit, a level conversion circuit, a dual-port RAM and a GJB289A bus protocol chip circuit.

[0018] 1553B bus interface circuit adopts JBU-61580 protocol chip. JBU-61580 integrates dual transceiver logic, codec, protocol logic, memory management and interrupt control logic, and also provides a 4K word (16bit) internal shared static RAM and a buffer interface with the processor bus; The software interface includes 17 internal operation registers, 8 test registers and a shared memory address space of 64K words; it works in the buffer mode and occupies a 16-bit data bus and a 12-bit address bus, and all its control signals are controlled by the decoding circuit of the FPGA Generated, communicate with F2812 through interrupt mode, so the interrupt pin INT of BU-61580 is connected with the external interrupt XINT1 ...

Abstract

The invention discloses a 1553B bus protocol module based on a DSP. The 1553B bus protocol module based on the DSP is used for solving the technical problem that a peripheral circuit of an existing 1553B bus interface card based on the DSP is complex. According to the technical scheme, the 1553B bus protocol module comprises a 1553B bus interface circuit, a logic synthesis circuit, a level switching circuit, a dual-port RAM and a GJB289A bus protocol chip circuit. The DSP with high performance is adopted as a control core and forms a minimum system with a peripheral auxiliary circuit. The function of a 1553B bus is achieved through a JBU61580 protocol chip, wherein the JBU61580 protocol chip provides rich resources for the design of a multi-path bus transmission interface and also provides extremely high flexibility and reliability for the design. Control and decoding of signals are realized through a FPGA. A peripheral circuit of an FPGA device is easy to connect and convenient to use. A powerful VerilogHDL language is used for programming, so that the maintainability and expansibility of the system are improved.

Description

technical field [0001] The invention relates to a 1553B bus protocol module, in particular to a 1553B bus protocol module based on DSP (Digital Signal Processing). Background technique [0002] The GJB289A bus (1553B bus) is an aircraft internal time-division command / response multiplexer with a transmission speed of 1Mb / s and a half-duplex mode proposed and developed by the United States in the late 1970s to meet the communication requirements of airborne equipment. Transmission data bus standard, because it can reduce the size, weight and complexity of electronic equipment, and has high reliability and real-time characteristics, it is widely used in aviation, ships, tanks, missiles, artificial satellites, international space stations and other mobile systems It is also widely used in the electronic equipment of the platform, and in the ground infrastructure such as test equipment and simulators. With the increasing performance of modern combat aircraft, it is required that...
