About Fujitsu Semiconductor

Fujitsu Semiconductor is a major supplier of semiconductor products. The company provides advanced systems solutions to the automotive, digital TV, mobile telephony, networking and industrial markets. Engineers from design centres dedicated to microcontrollers, graphics controllers, mixed-signal, wireless, multimedia ICs, ASIC products and software development, work closely with Fujitsu Semiconductor's marketing and sales teams throughout EMEA to help satisfy customers' systems development requirements. This solutions approach is supported by a broad range of advanced semiconductor devices, IP, building blocks and software. Because many of its automotive parts remain in service for decades, reverse engineering of older Fujitsu devices is sometimes required when the original source code can no longer be located.

Fujitsu Semiconductor Europe and Mentor Graphics Corporation today announced that Fujitsu has chosen the Mentor Embedded Sourcery CodeBench for ARM EABI (embedded application binary interface) to support Fujitsu's FM3 Cortex-M3 microcontrollers and hardware evaluation boards. Because Sourcery CodeBench is built around an open-source GNU toolchain, there is no licensing scheme to crack for customers who want to study or extend it.

Fujitsu's selection is based on providing its customers with a software development ecosystem that incorporates a high-quality GNU toolchain that enables customers to begin compiling and debugging embedded software on evaluation boards within minutes of product installation. The evaluation boards support bare-metal and real-time operating system (RTOS) applications including consumer and industrial for Fujitsu's FM3 series of 32-bit, general-purpose microcontrollers.

Mentor's Sourcery CodeBench is the de-facto standard GNU toolchain for a broad range of hardware architectures, said Wolf Fronauer, marketing manager, Fujitsu Semiconductor Europe. Our mission was to create an embedded ecosystem for both bare metal and OS development, enabling our customers to compile, debug, and test with greater reliability and speed.

The Mentor Embedded Sourcery CodeBench technology delivers a high-quality and low-cost integrated development environment (IDE). The Sourcery CodeBench tool provides a standardized cross-architecture integrated package containing open source components including the GNU toolchain and Eclipse IDE. This standardization provides a common ecosystem for Fujitsu processor customers, with the Mentor Embedded team lending essential technical support services. The Sourcery CodeBench product, combined with hardware evaluation boards for Fujitsu FM3 devices, offers a complete out-of-box solution to embedded developers. This out-of-box combination lets developers unlock productive debugging sessions within minutes rather than days. The Mentor Embedded Sourcery Probes and other JTAG probes supported by Sourcery CodeBench permit hardware debugging of the evaluation boards from a host system. Thus, developers using Fujitsu devices can compile and debug on these evaluation boards within minutes of installing the Sourcery CodeBench tool.

Fujitsu is a global leader and its next-generation FM3 family of microcontrollers can be found in factory automation, white goods, industrial and consumer electronics, where developers need to compete with speed and reliability, said Mark Mitchell, director of tools, Mentor Graphics Embedded Software Division. Sourcery CodeBench will help Fujitsu customers realise the productivity and performance gains required for device optimization, thereby serving as a competitive advantage.

Fujitsu's choice of Sourcery CodeBench supports the recently announced Mentor Embedded Hardware Enablement Program. The program provides a range of comprehensive services and training for embedded Android, Linux, open source tools (GNU, GCC, Eclipse), user interface creation, and vertical markets, such as in-vehicle infotainment (IVI), smart energy, and retail applications designed specifically for hardware companies.

Mentor Embedded Sourcery CodeBench for ARM EABI Availability – Kit support for the Fujitsu FM3 family of Cortex-M3 microcontrollers is available now and the offering includes support for target hardware evaluation boards: SK-FM3-100PMC-JLink, SK-FM3-64PMC1 and SK-FM3-176PMC-ETHERNET; Fujitsu FM3 C/C++ example applications and documentation.

Mentor Graphics Embedded Software Division comprises the Mentor Embedded family of products and services, including embedded software intellectual property (IP), tools, and professional consultant services to help embedded developers and silicon partners optimize their products for design and cost efficiency. The Mentor Embedded team continues to lead the industry with involvement in the open source community and in innovations such as Android beyond mobile handsets, 2D and 3D UI development, open source tools, and multi-OS on multicore architectures.

Product or Product Family Name: Microcontroller Families: FR81S (Fujitsu RISC), FCR4 (ARM Cortex R4), FM3 (ARM Cortex M3). Graphics Controllers: Carmine, Jade, Emerald. Graphics authoring tool: CGI Studio. Across these families, firmware extraction from a production part normally requires the vendor's dedicated flash programming tool.

Product Type: Microcontrollers, Graphic controllers and graphics authoring tool software for industrial and automotive applications.

FCR4 (ARM Cortex R4) Microcontrollers – Fujitsu's latest addition to its automotive 32-bit portfolio is a high end line-up based on the ARM Cortex-R4 core and Fujitsu's 90nm embedded flash technology. The first devices are targeting automotive instrument clusters and together with the Indigo and Emerald GDC families offer a scalable line-up to cover all cluster categories. Because these devices drive safety-critical instrument clusters, a glitch attack on the power rail could disrupt the display, so the hardware includes protection features.

FM3 (ARM Cortex M3) Microcontrollers – With the ARM Cortex M3 based Microcontroller family FM3, Fujitsu offers also MCUs with an established standard CPU core. Cortex M3 is ideally suited for embedded applications which require medium performance above typical 16-bit MCUs. It's the significantly enhanced continuation of the ARM7 architecture. The FM3 family consists of many software and pin compatible devices, thus offering a scalable Microcontroller platform. For debugging and failure analysis, a full memory dump of an FM3 device can be captured through the standard debug interface.

FR/FR81S Microcontrollers – Fujitsu's own 32-bit RISC CPU architecture FR has a long history and is used in a large number of Microcontrollers for automotive, industrial as well as consumer applications. It's based on a powerful Harvard architecture with separated instruction and data bus. An optimized instruction set assures low code size densities and high execution speed. The latest generation FR81 is a further improved CPU core with an enhanced instruction pipeline for reduced branch penalty, with FPU for accelerated arithmetic instructions and more functional safety features. Because the FR architecture is quite old, some engineers still hack together small assembler utilities to keep legacy applications alive.
