CAES GR740 has received QML-V and QML-Q certification from the Defence Logistics Agency

Aerospace and defence electronics specialist, CAES, has completed environmental testing on its fault tolerant GR740 quad core LEON 4FT processor device, which now has a US “Defense Logistics Agency” (DLA) qualification and can continue to meet some of the most demanding processing challenges of future space missions.

The device can now be ordered to a Standard Military Drawing (SMD) 5962-21204. The processor has both QML-V and QML-Q military standard quality certification and are ideal for spacecraft on-board computers, payload processing, high altitude avionics or other high reliability radiation hardened aerospace applications.

The GR740 device is a System-on-Chip (SoC) component featuring a quad-core fault-tolerant LEON4 SPARC V8 processor, eight port SpaceWire router, PCI initiator/target interface, CAN 2.0 interfaces and 10/100/1000 Mbit Ethernet interfaces. It provides the LEON families’ highest performance to date with a wide range of interfaces. The SoC has an excellent performance-to-watt ratio; less than 3 W (core typical) with 1000 MIPS (1700 DMIPS) performance. The device is targeted at high-performance general-purpose processing. The architecture is suitable for both symmetric and asymmetric multiprocessing. Shared resources can be monitored to support mixed-criticality applications.

According to Mike Elias, Senior Vice President and General Manager of Space Systems Division at CAES, the company is dedicated to providing radiation hardened computing systems to meet the space industry’s most stringent quality and screening levels.

“We are excited to see our highest multi-core microprocessor reach this key milestone as we continue to support our customers’ most demanding space missions,” he says.

The device joins the company’s existing line of LEON technology with built-in space application robustness, including the UT699, UT699E and UT700, single core LEON 3FT (prior generation) processors, and the dual core GR712RC.
