The GR-VPX-GR740 development board has been designed to support the development and fast prototyping of systems based on the Cobham Gaisler GR740 quad-core 32-bit fault-tolerant LEON4FT SPARC V8 processor. With the GR-VPX-GR740 Development Board Cobham Gaisler introduces a high performance Single-Board Computer for use within OpenVPX and SpaceVPX environments.
Based on the Cobham Gaisler GR740 Quad-Core 32-bit LEON4FT SPARC V8 processor, the GR-VPX-GR740 board comes in a 6U VPX format (233.5 mm x 160 mm) and is intended for use in OpenVPX chassis occupying a 1” slot (including mezzanine board). The board can also be used in stand-alone operation with a single 12V supply, in this case with limited VPX functionality.
The board is equipped with on-board memories for boot and application storage, and an SODIMM for SDRAM. The front panel includes basic communication interfaces and LED indicators, whereas the rear connectors are intended for OpenVPX/SpaceVPX backplane connections. A HPC-400 FMC connector for FPGA or other mezzanine boards provides interfaces with PCI, 3xSpaceWire and GPIO of the processor. It also connects to the Data Plane of the backplane via two Fat Pipes (8 differential pairs each) and four Thin Pipes (4 differential pairs each). Further signals routed between the mezzanine connector and the backplane include two Thin Pipes to the Control Plane and other system control signals.
The board is developed to be used as a Switch Module in the OpenVPX architecture based on ANSI/VITA 65.0-2017. It can also be ordered as a factory-configured variant with the backplane interface designed as a Switch and Controller Module providing some of the features of the SpaceVPX architecture specified in the Draft ANSI/VITA 78.00-2015. See details in the Product Sheet.
