AIMS -GENERAL DESCRIPTION -1
AIMS Cabinets
The AIMS has two cabinets which do the calculations for other avionic systems. To do these calculations, each AIMS cabinet has these:
*
A cabinet chassis
*
Four Input/output modules (IOM)
*
Four Core processor modules (CPM).
The IOMs and the CPMs are in the cabinet chassis. The chassis also has a backplane data bus and a backplane power bus to distribute data and power to the IOMs and CPMs.
The input/output module (IOM) transfers data between the software functions in the AIMS CPMs and external signal sources.
The CPMs supply the software and hardware to do the calculations for several avionic systems. The software is called functions. To keep a necessary separation between the functions, each function is partitioned. The partitions permit multiple functions to use the same hardware and be in the same CPM.
These are the four types of CPMs:
*
CPM/Communication (CPM/Comm)
*
CPM/Airplane condition monitoring function (CPM/ACMF) (left AIMS cabinet only)
*
CPM/Basic (right AIMS cabinet only)
*
CPM/Graphics generator (CPM/GG).
CPM Functions
These are the software functions in the CPM/Comm:
*
Data conversion gateway function (DCGF)
*
Central maintenance computing function (CMCF)
*
Data communication management function (DCMF)
*
Flight deck communication function (FDCF)
