System on chip adopting ARINC 659 rear panel data bus interface chip

Abstract

The invention provides a system on a chip adopting an ARINC 659 rear panel data bus interface chip with high reliability and credibility and low cost in a novel communication mechanism. The system on the chip comprises a PCI (Peripheral Component Interconnect) bus interface module, a two-port RAM, a bus command list mapping storage, a command list self-loading functional module and an ARINC 659 bus protocol processing module. The invention ensures complete certainty of the communication.

Description

technical field [0001] The invention belongs to the field of computer communication, and relates to an ARINC 659 backplane data bus interface chip on-chip system. Background technique [0002] ARINC 659 backplane data bus (hereinafter referred to as: ARINC 659 bus) is a fault-tolerant serial bus with dual-dual redundancy configuration based on time-triggered architecture. It supports robust time partition and space partition. It is a comprehensive modular avionics The key technology of the system. The ARINC 659 bus is derived from Honeywell's SAFEBus TM Bus, 1993, SAFEBus TM The bus was adopted by the Society of Aeronautical Electronics Engineers (AEEC) and became a standard, promulgated as the ARINC 659 backplane bus specification. Among the currently applied aviation data buses, the reliability, integrity and redundancy levels provided by the ARINC 659 bus are the highest. [0003] The ARINC 659 bus has been used in Boeing 777's Airplane Information Management System (...
