Fuchsia Open Source Operating System uses a new Magenta kernel, which is designed to compete with IoT-oriented operating systems like FreeRTOS or ThreadX. The special feature that the Magenta kernel is designed to work with smartphones, desktop computers and Internet of things.
Fuchsia Open Source
Fuchsia is not built on linux kernel, instead magenta kernel is used. And it seems able to run on all devices. OS is built using Dart programming language. Flutter support indicates that the OS will likely use Material Design for its user interface.
It has support for both 32-bit and 64-bit ARM CPUs, as well as 64-bit PCs. You can even compile it yourself and run it on a real PC or a virtual machine.
So, Why is Google quietly developing a brand new OS and kernel, with support for smartphones and PCs, possibly built with Material Design in mind? The most obvious guess is that Google hopes to one day replace Chrome OS and Android with Fuchsia.
Not a Linux Based Kernel
Every software developed by Google has one thing in common that is, they’re based on the Linux kernel. Chrome OS, Android, Chromecasts, etc. Linux has powered Google hardware for years. But the Linux kernel is not ideal for every devices. Devices like car dashboards or GPS units, full-blown desktop kernels like Linux impact performance and cause other issues.
