Abstract: |
The high-deterministic and reliable AS5643 protocol is introduced and an
alyzed.In order to release the processors from complex protocol, the implementa
tion of AS5643 protocol based on FPGA (Field Programmable Gate Array) is propose
d, and the system design and VHDL (Very-High-Speed Integrated Circuit Hardware
Description Language) implementation of the protocol module are explained in detail.
Experiments show that the realized module based on FPGA is in accordance with t
he AS5643 protocol standard. This module can be used in integrated avionic sy
stems which require high-performance serial bus. |
