Nucleus RTOS is a real-time operating system (RTOS) and toolset created by the Embedded Systems 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 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 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.

Components

Kernel

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

Connectivity

USB 2.0 Host, Function and On-The-Go (OTG) stacks
Class drivers
Bluetooth with many advanced profiles enabled (A2DP, AVRCP, HFP, HSP, etc.)
Multimedia transfer (MTP and PictBridge)
PCI and PCI-X
CAN and CANopen
Over 60 network drivers and protocols including TCP/IP stack, IPv6 and IEEE 802.11 wireless

File System

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

Graphics

Low-level rendering
Windowing system
Multi-media GUI control framework

Security

Encryption
Hash and signature algorithms
Key exchange protocols

Products using Nucleus RTOS

Mentor Graphics boasts Nucleus installment base of over 1.6 billion mobile devices,^[3] as of mid-February, 2010 and 2.11 billion devices as of June 2010. According to a report^[4] by an analyst firm, Nucleus has been shipped in over 2.84 billion devices as of the end of 2010.
