Nucleus RTOS Reviews & Product Details

Best part is it modularity and the support for priority inheritance. The entire system is modularized and this helps in easy porting to different Modules.

The file system provided by the nucleus was good in the sense it supported the Power fail system it was very important for the embedded system and this helped in saving the contents when the power goes and this helped us a lot.

Also the drivers were cleanly written and the test cases was very easy to develop. There was also support for the IOT based system where the support for POSIX was there. When you have support for POSIX this means your software will readily blend to it , Most of the the software is written in linux and this means that the Code will inherently ready to blend with the Nucleus RTOS

Nucleus SmartFit from Mentor Graphics Corporation is a binary version of the Nucleus RTOS optimized to fit the limited internal memory of 32-bit MCUs. Nucleus SmartFit includes Sourcery CodeBench development tools and provides developers with broad connectivity and power consumption options for developing products based on 32-bit MCUs.

Included in the Nucleus RTOS is the Power Management Framework with which developers can maximize battery life in power-efficient applications. In addition to Sourcery CodeBench development tools, the Nucleus SmartFit platform can be configured to include I/O and bus support, file systems, networking IPv4/IPv6, wireless, and USB functionality. The Nucleus SmartFit product is suited for medical and personal healthcare, smart grid, industrial sensors, and white goods products..

The Debug agent is a bit slow and this creates problem. The BDI Agent provided is not that efficient.

The Boot loader provided by the Nucleus was not that easy to work with. We had to use trace 32 for this purpose and they will promote use to use the BDI agent please dont go with that.

The Sourcery code bench is a bit slow and this is not useful for debugging unlike the one given by the qNX

The RTOS was bit failed in priority inversion tests. Review collected by and hosted on G2.com.

I had used Nucleus RTOS in Validating the Power distribution system in Aerospace industry . And also currently using it in a Embedded (Electric drive) field. There are few points for which i felt it as one of the best in market .

It supports Power PC architecture, which was used in our project secondary power distribution assembly of an aircraft. Nucleus is used to provide an environment to allow multiple tasks toexecute on a single CPU which includes providing a system where time (task execution) and space (memory) are partitioned to allow different levels of criticality software to be independent.. It also provides inter-task communication in an atomic fashion. As it is lightweight it is easy to use for a space partitioning system. one more major plus point is it works well with all mainly used embedded architecture which is important for a system to fit in any environment if in case any future changes required. The latest Nucleus supports advanced UI features and the optimized code of the framework helps in faster debugging. Review collected by and hosted on G2.com.

For any product improvisation is very important which comes as the time moves on.

As we all know the future of embedded systems is IOT as of now . Apart from it i dont have any dislikes in this as of now but yes in future lot of improvements will come. Review collected by and hosted on G2.com.

Nucleus has a broad set of BSPs available off the shelf that will help you to reduce time to market for your product. The driver support is also rich and contain all peripheral driver e.g. UART, I2C, SPI, Gyroscope, CRC engine, interrupt controllers, PLLs, ethernet, NAND \ NOR flashes, CAN, LIN, Touch panel and display etc.

Even if you have a custom board, the drivers are super easy to develop because driver interface is highly influenced by baremetal development mind set.

Nucleus support different hardware architectures e.g. ARM, PowerPC, MIPS and many more.

Apart from that Nucleus latency time is very short. The scheduling latency is as low as 6 usec which makes it favorable for time critical applications. Review collected by and hosted on G2.com.

The software stack of Nucleus is a bit complex and can be buggy. There has to be a simpler, more efficient software stack to develop IOT based products.

The reason for complexity is the need to develop a software stack that fits the broad portfolio of Nucleus based products like MEMF, Hypervisor etc. but in most cases it is not required by user.

The process model support is also not very mature. Review collected by and hosted on G2.com.

The power management options available are excellent and go in hand with many of the advanced MCUs and MPUs. Review collected by and hosted on G2.com.

Requirements to run the kernel is pretty heavy, a Beta version would plug this gap. Review collected by and hosted on G2.com.

We had used nucleus RTOS for our 2G/3G/4G protocol stack Development.

I felt the code is written in an optimized manner and easy to understand.it was very easy to make our protocol stack run on top of nucleus RTOS.

Multicore support with SMP helped us to structure our protocol stack and distribute the tasks to different cores so that we could achieve minimum latency.

Memory footprint was very small compared to other Free open source Rtos's available.

We were developing our own RTOS (to reduce the licensing complications ) Nuclues RTOS helped us very much to clearly understand how to design and develop an RTOS from scratch. Review collected by and hosted on G2.com.

We had used Nuclues RTOS back in 2012 to 2015, to be honest we dint find anything to dislike about it,it included all the features which were necessary for our product,it has evolved a lot from then. It includes IOT framework support with which the possibilities are endless. Review collected by and hosted on G2.com.

Easy to understand and easy to use the APIs provided. Size of library is small as it does not include complete concepts of generic OS. Review collected by and hosted on G2.com.

Nucleus is perfectly structured. no need for changes Review collected by and hosted on G2.com.

It’s user manual is self explanatory so that anyone can understand and use the RTOS services efficiently.. it’s memory foot print is also less and its best suitable for embedded application development Review collected by and hosted on G2.com.

Profiling statistics could be better and brief Review collected by and hosted on G2.com.

It has full stack for both networking and USB. Smooth switching between threads and context switching. Well defined API's. Got good support team Review collected by and hosted on G2.com.

The only problem I seen is at the time I work on this it don't have full pledged wirless stack support. Review collected by and hosted on G2.com.

Its layered Architecture makes easy for users to do understand and implement features Review collected by and hosted on G2.com.

Need to provide simple way of module access through APIs Review collected by and hosted on G2.com.

Nucleus RTOS is a well designed RTOS and is properly supported by excellent documentation.

Have been using this RTOS for past 9 years on embedded infotainment products.

Would recommend this RTOS for embedded products. Review collected by and hosted on G2.com.

For UI had to use customize designed UI Framework.

Felt lagged to support for rich UI framework with performance, but I hope mentor graphics might have supported in the latest versions of Nucleus RTOS Review collected by and hosted on G2.com.
