Abstract

The present invention provides a kind of ARINC659 bus controller with embedded micro-controller, comprising 8051 core, Local_bus host interface, BIU (Bus Interface Unit, bus interface unit) control unit, BIU module, BIU on-chip memory access interface, MTM ( Module Test and Maintenance) bus control module, general input and output interface; each module in the chip is interconnected through a custom on-chip bus to form a system on chip. The invention can meet the aerospace application of the high-reliability backplane bus ARINC 659, and is embedded with 8051 processor and general digital interface logic, and has important application value for improving the real-time performance, reliability and integration degree of the comprehensive electronic system of the spacecraft.

Description

technical field [0001] The invention relates to the technical field of aerospace digital integration, in particular to an ARINC659 bus controller embedded with a microcontroller, in particular to an ARINC659 bus interface chip embedded with a microcontroller. Background technique [0002] The reliability of ARINC 659 bus is much higher than that of general bus, and the safety of fault automatic isolation. At the same time, it encapsulates the physical layer and the data link layer and shields the mechanisms of addressing, synchronization, demarcation, and error control from the upper layer, so that the latter can focus more on the effective data itself for communication, simplifying its work and improving efficiency . Therefore, it can better meet the reliability, security and high-throughput communication requirements of the spacecraft integrated electronic system for the backplane bus. Because of this, its space application has received great attention both at home and a...
