1.) What is Codezero?
|
| 17 |
|
|
|
| 18 |
|
|
Codezero is an L4 microkernel that has been written from scratch. It targets
|
| 19 |
|
|
embedded systems and its purpose is to act as a secure embedded hypervisor. It
|
| 20 |
|
|
aims to become the most modern L4 implementation by evolving the L4 microkernel
|
| 21 |
|
|
API into the future. In a nutshell, Codezero provides all the basic mechanism
|
| 22 |
|
|
to abstract away the hardware, build OS services, isolate applications and
|
| 23 |
|
|
fine-grain security in a single package.

|
2.) Why the name Codezero?
|
| 27 |
|
|
|
| 28 |
|
|
The project philosophy is to create the simplest and leanest microkernel that
|
| 29 |
|
|
is generic and applicable to many different applications. Feature creep is what
|
| 30 |
|
|
we don't have in Codezero. Simple, elegant design is the project philosophy.
|
| 31 |
|
|
|

|
|
3.) Why use Codezero?
|
| 34 |
|
|
|
| 35 |
|
|
Codezero aims to be technically cutting-edge. It's design is open and improves
|
| 36 |
|
|
by evolution. It is also easy-to-use, well-documented and portable, mostly
|
| 37 |
|
|
maturing on the ARM architecture. These might be the appealing reasons from a
|
| 38 |
|
|
technical point-of-view. It is also backed by a responsive team, in case you
|
| 39 |
|
|
have more demanding requirements.
