Fujitsu Laboratories develops fast simulation technology able to faithfully reproduce CPU operations

Supplier News

Fujitsu Microelectronics, Asia  announces a new simulation technology for systems using the ARM computing core, widely used in mobile phones and various electronic devices.

The extremely fast simulation technology can faithfully reproduce hardware operations with cycle-for-cycle real-time accuracy, allowing the development cycle for systems and devices using ARM cores to be shortened while encouraging the development of a greater diversity of ARM-based systems.

Increasingly complex systems using the ARM core such as mobile phones and electronic devices require a simulation technology that runs faster and with better fidelity to the hardware, for use in testing as well as in application and operating system development.

Fujitsu’s new platform for running simulations runs as fast as a JIT compiler but with precise cycle-level fidelity, allowing a standard PC environment to simulate an ARM multicore system at speeds faster than 100 MHz at the cycle level, representing a hundredfold speedup over previous simulators.

Key features of the new simulation technology:

  • JIT compiler technology with cycle-level precision enables the simulator to run fast and with fidelity to the way the code would run on its native hardware
  • Multicore-compatible technology performs separate real-time calculations for each core, enabling load distribution that levels the load of each core
  • Shortens the development cycle for systems and devices using ARM cores
  • Encourages the development of a greater diversity of ARM-based systems
