Paragon Software Group (PSG) has launched the Paragon Universal File Systems Drive (UFSD) for Nucleus, a technology that grants instant access to popular macOS, Linux, or Windows-formatted file systems under Nucleus OS.

More than three billion devices throughout the world run today on the Nucleus real-time operating system (RTOS). Nucleus OS includes a FAT-compatible file system data storage tailored specifically for embedded applications. Although the Nucleus file system could be used for various applications, other file systems, such as Windows NTFS, exFAT, Mac HFS+, and Linux extFS are more popular and widely used today.

Paragon UFSD for Nucleus provides full support for Windows, macOS and Linux file systems, opening up new opportunities for embedded system builders, while making their devices compatible, faster, more reliable, and flexible. Embedded developers are no longer limited to obsolete FAT and can now implement any popular file system on resource-constrained, energy-efficient devices that run at low speeds.

Key features

  • Read/write access to FAT, NTFS, exFAT, HFS+, and extFS-formatted volumes under Nucleus OS.
  • The company claims high data throughput equivalent to or exceeding native file system performance.
  • Tested in different configurations to ensure there are no file or volume corruptions.
  • Support of multiple partitions on a block device. Includes functionality for working with several storage partitions at once.
  • Supports the following internal and external storage devices: SATA HDD, USB-HDD, SSD, SD cards, etc.

The UFSD for Nucleus OS comes in the form of a binary library, which is linked when the firmware is compiled. Depending on the platform, additional modifications to Nucleus kernel code may be necessary. Since most vendors modify Nucleus OS according to their needs, Paragon provides assistance with integration.
