Sparrow is an embedded operating system.
Now it supports S3C6410X chipset (ARM architecture) only, and run in Skyeye simulator.
The name "Sparrow" comes from a famous Chinese proverb - "Sparrow may be small but perfectly formed". I hope it has every important features of modern system, but not too complex.
To share the knowledge how an operating system is created, I compiled some document. But usually design document is always boring, so I made as many diagrams as possible to illustrate the most important mechanism. Hope the cartoon-style document let the readers feel relaxed. These slides are also available in doc folder of the repository.
