Microprocessor | Frontgrade

Overview

Based on the industry-standard SPARC V8 architecture, the UT700 32-bit Fault Tolerant microprocessor is a system-on-chip and features a seven-stage pipelined monolithic, high performance, fault-tolerant SPARC V8/LEON3FT Processor.

The UT700 is part of the LEON product family that has a long lineage in the space industry.

Targeted for applications such as spacecraft on-board computers, payload processing, nuclear power plant controllers, critical transportation systems, high-altitude avionics, and medical electronics and X-ray cargo scanning.

Frontgrade's UT700 LEON3FT is SPARC V8 compliant so developers may use industry standard compilers, kernels and development tools. A full software development suite is available.

UT700-LEAP

The Frontgrade UT700-LEAP evaluation board and mezzanine companion cards provides a flexible development platform for customers for accelerated development at a minimal cost. The LEAP has a Frontgrade UT700 LEON 3 FT prototype grade device with 8 Mbytes NV memory storage and 32Mbytes SDRAM (both commercial memory), along with one USB UART interface and one 10T/100 Mbit/s Ethernet port. It also includes a JTAG interface for programming and debug of UT700 LEON 3FT (requires XILINX USB Platform Cable) along with one 192-pin mezzanine card expansion connector and an on-board Programmable LEAP main clock.

Software Development Tools

Frontgrade Gaisler’s comprehensive software ecosystem includes Bare-C and RTEMS toolchain, Linux, VxWorks, and Zephyr operating system support, TSIM2/3 simulators, GRMON3 debugger, boot loaders and hypervisor support for rapid development support. Template designs are available and portable between technologies. Used to create SoC designs based around the microprocessor core, the LEON and NOEL-V processor models are integrated in the GRLIB IP library.
