Processor Architectures

The foundation for performance, efficiency, and scalability

Processor architectures define the computing power and energy efficiency of modern embedded systems. They form the basis for applications in industry, critical infrastructure, and defense, where reliability is essential. The choice of architecture affects not only performance but also integration capabilities and long-term availability. iesy relies on established and future-proof platforms to create a sustainable, application-optimized foundation.

Our standards at a glance

  • x86-architecture – powerful and versatile for complex operating systems and virtualization
  • ARM-architecture – energy-efficient and scalable for mobile and edge applications
  • 32-bit microcontrollers (MCU) – compact and energy-efficient for embedded control and real-time applications
  • FPGA-based architectures – reconfigurable hardware platforms for maximum flexibility and hardware acceleration
  • RISC-V – open, license-free, and future-oriented architecture for flexible, modular designs

iesy expertise

  • iesy brings more than 30 years of experience with processor architectures for industrial applications. We have been developing embedded computers since 1990, initially based on the then still rare x86 architecture.
  • Starting with the Intel XScale architecture, ARM-based architectures have been part of our portfolio since 2010.
  • Our specific expertise includes the use and adaptation of embedded operating systems such as RTOS Linux (since 2001), Gentoo Linux (since 2012), Yocto Linux (since 2018), and various embedded Windows derivatives (since 2006).
  • Architectures such as FPGA, CPLD, and MCU have been continuously used for decades, giving us in-depth know-how, particularly for energy-optimized and real-time applications, often in combination with other architectures.

Additional context – concise and to the point.

The Future of RISC-V

RISC-V is evolving into a key technology in the embedded domain. As an open, license-free architecture, it enables customized designs without dependency on proprietary platforms. Growing support from industry and the open-source community makes RISC-V a future-proof alternative for safety-critical applications.

AI Acceleration and its Impact on Processor Architectures

x86 architectures integrate extensions such as AVX-512 or AMX, ARM leverages Neoverse and Cortex-A designs with AI cores, and RISC-V extends its ISA with vector processing and machine learning capabilities. These developments shorten processing times and enable edge devices to perform complex analytics locally – without relying on the cloud.

Consortia and Standardization Bodies

Organizations such as the RISC-V International Consortium drive open standards. Proprietary platform vendors dominate x86 and ARM, while FPGA standards are shaped by bodies like IEEE and JEDEC. These organizations ensure compatibility, long-term availability, and interoperability.
