GR740 Development Status

The development of the rad-hard GR740 quad-core LEON4FT microprocessor has now been completed and the product with the ceramic package has achieved QML-V qualification earlier this year. In parallel the development of the organic package is progressing and the evaluation and lot validation is being completed. The presentation will cover the functionality of the GR740 and development status of both package variants.

SCS3740 Rad Hard SBC and Next Gen SBC using the GR740

DDC has been designing components and single board computers (SBC) for the space market for over 25 years. Our SCS3740 Rad Hard SBC has been optimized for radiation tolerance, low power in a 3U SpaceVPX form factor. DDC will be presenting the present SCS3740 board, as well as the new SCS3740G2 (2nd Generation) board with memory upgrades in density and performance, along with a description of some of the components used with the GR740.

Hybrid OpenVPX/SpaceVPX Payload Processors using the GR740

Los Alamos National Laboratory has developed and built both 6U and 3U payload processor modules based on the CAES Gaisler GR740 microprocessor that implement a hybridization of OpenVPX and SpaceVPX to aid with interoperability and provide support for higher performance protocols in the future. A key to this flexibility is the use of a Microchip RTG4 FPGA that augments the capabilities of the GR740 and allows for application-specific hardware customizations through changes in FPGA firmware. We will discuss the architectures and features of the boards and our lessons learned regarding our use of the GR740 in these designs.

GR765 Development Status

Based on feedback from current GR740 users, Cobham Gaisler develops the successor, under the product name “GR765”. The GR765 architecture includes several improvements over the GR740. The LEON4FT has been replaced with the LEON5FT high-performance processor, increasing computational performance while at the same time providing a low-threshold upgrade path for current GR740 users that require more computational performance or that would benefit from the added on-chip functionality of the new architecture.

The driver for the GR765 was to provide a next step for current LEON-SPARC GR740 users. At the same time, the RISC-V instruction set architecture has generated significant interest within essentially all industries, including space. To rapidly introduce RISC-V in the space domain, going beyond use of COTS or FPGA implementations, the GR765 architecture was extended with an additional mode where the eight active processor cores can either be NOEL-V RISC-V RV64GCHB processors or LEON5FT SPARC V8e processors.

The GR765 will be implemented on STMicroelectronics 28nm FDSOI technology using libraries developed by STM for use in space applications. Improvements in processor microarchitecture, bandwidth of the system-on-chip design, and operating frequency are expected to improve the computational capacity 10x – 16x compared to the GR740. In addition, the GR765 will provide significant reductions in power consumption compared to earlier generation SoCs.

Beyond this boost on processing performance, the memory bandwidth will also be significantly increased by the use of DDR2/3 SDRAM, the peripherals will be complemented by SerDes supporting among others the SpaceFibre standard, TTEthernet, TSN and several other enhancements.
