Nucleus RTOS is a real-time operating system (RTOS) offered by the Embedded Software Division of Mentor Graphics for various central processing unit (CPU) platforms. Nucleus RTOS is embedded software and is in an estimated 2.11 billion devices worldwide.[2]

Development is typically done on a host computer running Windows or Linux. Applications are cross compiled to run on various target CPU architectures and tested using the actual target boards or in simulation environment.

The Nucleus RTOS is designed for deeply embedded systems applications including consumer electronics, set-top boxes, cellular phones, and other portable and handheld devices. For limited memory systems Nucleus RTOS can be scaled down to a memory footprint as small as 13 KB for both code and data.[citation needed]

Components

Kernel

  • Real time kernel
  • Microkernel based design [3]
  • C++, POSIX and Micro ITRON interfaces
  • Dynamic download
  • Inter-process communication
  • Closed Source (however, the source code is available to customers, making it easier to debug than operating system distributed as binaries only)

Connectivity

File System

  • File Allocation Table (FAT)
  • CD-ROM
  • Virtual file system Application Programming Interface (API)

Graphics

Security

  • Encryption
  • Hash and signature algorithms
  • Key exchange protocols
