Implementation of ARINC 659 Bus Controller for Space-Borne Computers

Abstract

As one of the key technologies of Honeywell, the aeronautical radio incorporated (ARINC) 659 bus is popular in current space-borne computers. However, Honeywell does not design ARINC 659 bus controller separately, and there are only a few papers about FPGA-based ARINC 659 bus controllers. Accordingly, to promote the extremely high performance needs of space-borne computers, this paper designs an ARINC 659 bus controller chip which integrates two independent bus interface units (BIUs), one 8-bit MCU, and several peripheral interfaces (i.e., UART, SPI, and I2C). Because the two BIUs are identical and mutually checked, the symmetry problem is emphatically dealt with in the design of this bus controller, and effective timing convergence is realized, which makes the bus controller work reliably and stably. In addition, due to the circuit’s large scale, design for testability (DFT) is also considered. Accordingly, on-chip clock (OCC) and scanning compression test technique are used to realize the at-speed test and shorten the test time, respectively.

Sequential-Fault Diagnosis Strategy for High-Speed Train Traction Systems Based on Unreliable Tests

“…Testability design comes into being with testing. Using design-for-testability (DFT) [7] can make a bus controller work more reliably and stably. One of the methods of DFT is scanning design [8][9][10][11], which can effectively improve the reliability of testing.…”

An Efficient Multi-Lane SpaceFibre Core for Spacecraft Data-Handling Networks

“…Spacecraft data-handling networks [1] are required to sustain multi-gigabit capabilities, due to the increasingly high data volume produced by high-rate payloads, such as hyperspectral imagers [2] and synthetic aperture radars [3]. The demand for high bandwidth leads to some limitations of single-lane standards [4][5][6][7][8][9], and some multi-lane standards [10] support only an even number of lane configurations. To enhance the data processing ability in a space environment, the European Space Agency developed the SpaceFibre [11] standard for interconnection networks designed for satellite payloads.…”
