S.O.O.S

(Server Oriented Operating System)

 

 


 

Description

 


 

S.O.O.S. is an operating system (OS) specially designed for embedded systems. S.O.O.S. has a modular structure based on layers.

Each layer and module provides a set of functions that facilitates the communication and hides the actual implementation. In this way,

it is possible to port the application to another hardware platform just by changing the appropriate layers.

S.O.O.S is based on the usage of servers, which encapsulate soft real-time tasks. In this sense, the task executes approximately

 as if it was on a virtual dedicated processor with speed lower than the one of the real processor. The use of servers provides also the

possibility of negotiate the quality of service of the application. If the server resembles exactly the minimum interarrival time and worst case

execution time, the task is guaranteed a hard real-time treatment. If this is not the case, a soft real-time guarantee is provided.

 The OS does not check the feasibility of the system but guarantees an appropriate behavior provided the tasks and server are properly configured.
