CDDI for AAAV Programme

CI Systems's conduction-cooled PMC (CCPMC) CDDI Adapter has been selected by Geneneral Dynamics Amphibious Systems (GDAMS) for the US Marines' Advanced Amphibious Assault Vehicle (AAAV) Programme.

The project involves ruggedising the PMC CDDI Adapater, which has been integrated with DY4's Level 100 PowerPC VME boards (DMV178) and Pentium VME boards (DMV190). CI Systems and DY4 have co-operated in the design and qualification of the conduction-cooled version of the PMC CDDI product.

CI Systems has developed VxWorks FDDI drivers in 4.3 BSD format. This allows any VxWorks application user to interface to the FDDI driver by using the standard VxWorks TCP/IP stack. The drivers are offered with all CI Systems' FDDI product ranges and compliment the already extensive library of drivers on offer. Built-In Test (BIT) software in VxWorks for PowerPC has been developed to test the hardware integrity of the PMC FDDI Adapter as there is a requirement to test 95% of the FDDI functionality.

Some of the stringent requirements placed on the CCPMC CDDI Adapter are :

  • Operating temperature : -40 C to +85 C
  • Low Power consumption : 1,45 A typically
  • Shock and vibration specifications for Ground Mobile Environment
  • High reliability : > 20 000 hours, MIL-HDBK-217F, Ground Mobile Environment
