Nucleus – a real-time operating system for the embedded systems market from Accelerated Technology (AT), acquired by Mentor Graphics in 2002.

There are different variants for different applications, such as Nucleus RTOS, Nucleus RTX and Nucleus PLUS with the associated Eclipse-based development environment Nucleus EDGE. The list of prominent OEM customers of this RTOS, which competes with QNX or VxWorks, for example, is therefore quite long: Apple, Creative, Garmin, Honeywell, Infineon, Intel, LG, LSI Logic, Motorola, NEC, Renesas, Samsung, Sony, Texas Instruments, Toshiba, Winbond.

Nucleus RTOS supports numerous processor platforms with a wide variety of ARM, MIPS, Power, PowerPC, SuperH and XScale architectures. The supported platforms and processor cores come from manufacturer-independent IP companies and semiconductor manufacturers. In addition to the companies already mentioned as software OEMs, these also include ARM, Atmel, Freescale, IBM, MIPS, STMicroelectronics, as well as the large FPGA manufacturers Altera (Nios II) and Xilinx (MicroBlaze, ZYNQ). A special feature is the good support of the various Motorola 68000 CPU derivatives and the good integration with development tools from Wind River Systems.
