Turnkey MEC is for avionics
02 September 2008
A rugged MEC (modular embedded computer) from Kontron is targeted at avionics applications.
The MEC-PPC-AV1 is a 3U CompactPCI rugged COTS sub-system, with low-power dissipation, real-time software and a large I/O provision.
The MEC architecture is a cost-effective CPTS sub-system argues the company, with a range of options to cover specific avionic needs. It has ATR footprint dimensions, a 28V DC power supply and is made of lightweight aluminium and has conduction-cooled dissipation, MIL-STD-1553 links, MIL-C-38999 connectors and consumes <17W.
The computer hosts a 3U CompactPCI single-slot PowerEngineC7 embedded computer, already used in avionics. The PowerEngineC7 can be used as a system slot or a peripheral slot processor board. It is based on the PowerPC G3 750FX RISC CPU, which has 512kByte internal cache and the Marvel Discovery III MV64460 integrated system controller. One processor is clocked at 700MHz and onboard memory is 512MByte with ECC. There are two on-board asynchronous serial lines and two 10/100BASE Ethernet channels as well as 64MByte system flash, 128kByte non-volatile SRAM with real clock and a 32 CompactPCI bus and 3233/66MHz PMC module.
I/Os include Ethernet, general-purpose I/Os, serial lines and MIL-STF-1553 links via the CMPC-1553-R PCI mezzanine. This is a redundant MIL-SD-1553B interface with two channels. Each channel has an ILC-DDC BU-61688 advanced communication engine and an 8kByte dual port RAM. It supports the bus controller, remote terminal or monitor terminal operating modes. The PMC module has a 32bit, 33MHz PCI and a parallel 8bit TTL I/O port.
The MEC is a turnkey system with pre-loaded VxWorks 6.2. The company’s VxWorks BSPs are certified by Wind River.
