31、data between Line Replaceable Modules (LRMs) within anIntegrated Modular Avionics (IMA) cabinet. Thisspecification defines the characteristics necessary tointerface with a general purpose backplane data bus forintra-cabinet communication. It defines the electricalcharacteristics and behavior expecte

32、d of the LRM and thebackplane where they meet at the LRM to backplaneconnectors.1.2 Document ScopeThis document defines the electrical characteristics for acontrolled impedance backplane bus for use withIntegrated Modular Avionics (IMA). It defines thenecessary characteristics of the bus that will e

33、nsureelectrical compatibility at the interface between theavionics module and the IMA cabinet. ARINCSpecification 659 defines the protocol, timing, bit rate andpower requirements for the physical backplane. It definesthe physical medium, physical layer and parts of theMedia Access Control (MAC) subl

34、ayer referred to in theOSI Reference Model.1.3 Relationship to Other Standards1.3.1 Other Data Bus StandardsARINC Specification 659 is intended to address intra-cabinet communications between LRMs within a cabinetconforming to ARINC Report 651. ARINC Specification659 satisfies unique IMA requirement

35、s for medium/highthroughput of data, strict fault isolation, and data transferdeterminism.ARINC Specification 659 addresses internal cabinetcommunications, thus complementing ARINCSpecifications 429, 629, 636, and 646, which addressexternal cabinet communications.1.3.2 IMA Packaging StandardsARINC 6

36、50 defines the physical-mechanical andenvironmental characteristics of an IMA cabinet. Thephysical-electrical characteristics defined in this documentare compatible with the worst case requirements permittedby ARINC 650 regarding the length of backplanetransmission data and the number and spacing of

37、backplane module connections.This document also details the specific pin allocations forthe ARINC 650 backplane connector field dedicated tointra-cabinet data transfer.1.4 ARINC Specification 659 Basic PhilosophyARINC Specification 659 defines a backplane datacommunication protocol which allows stan

38、dard avionicsLRMs to transmit and receive digital data within acommon cabinet. The concepts for this cabinet aredescribed by ARINC Report 651, “Design Guidance forIntegrated Modular Avionics (IMA)“.The IMA concepts include the use of common resourcesshared among several functions within a cabinet. T

39、hesefunctions may be separated into independent partitions.To preserve the independence, it is imperative that nopartition adversely affect another partition, no matter howfaulty its design or behavior. This is called robustpartitioning. In particular, the access to shared resourcesmust not deviate

40、in any way from its designed allocation(even if IMA components are faulty). This is calleddeterminism.The backplane bus is a key shared resource. ARINCSpecification 659 provides for its determinism through theuse of the Table Driven Proportional Access (TDPA)protocol. It also enforces elements of ro

41、bust partitioningamong the LRMs it serves.To support the operational goals of the IMA cabinet, thebackplane bus must provide a high level of reliability andfault tolerance. Reliability is realized through minimizationof logic and bus lines. Fault tolerance, defined as theability to provide a needed

42、function and to continueoperation in a specified manner after one or more faultshave occurred, is provided through high coverage faultdetection, fault containment, and redundancy.1.5 ARINC Specification 659 OverviewThis document is organized into four sections, fourattachments, and an appendix.Secti

43、on 1 provides this introduction and general overviewof ARINC Specification 659, and points out relatedARINC documents.Section 2 provides a technical overview of ARINCSpecification 659. Basic architecture, robust partitioning,supported data types and error management features of thebus are described.

44、Section 3 provides detailed implementation description ofthe bus physical layer. This includes mechanical,electrical, and data line definition.Section 4 provides detailed description of the datatransfer protocol, including data format, operation duringsynchronization and loss of synchronization, ini

45、tialization,and error handling.Attachment 1 is the glossary. Attachments 2 through 4provide figures and other amplifying material for sections2 through 4, respectively.Appendix A describes the bus debug feature.1.6 Support of ARINC Report 651Many of the goals and objectives of ARINC Report 651are em

46、bodied in the backplane bus. The specificobjectives are broad in scope. Some of the salientfeatures of ARINC Specification 659 which supportARINC Report 651 are listed below:Support of robust partitioning, enabling reliablecontrol of shared resourcesARINC SPECIFICATION 659 - Page 21.0 INTRODUCTION (
