Abstract

A software communication architecture (SCA)-based system includes a plurality of components and a relay component connected to the plurality of components. Since data among the components are transmitted through the relay component, it is possible to reduce the complexity of connection caused by an increase in the number of components and to prevent a file size from increasing. Therefore, it is possible to reduce the parsing time of a domain profile and to reduce mode exchange time so that it is possible to rapidly perform connection setups in an embedded environment and to effectively perform communication.

Claims

1. A system based on software communication architecture (SCA), comprising a processor configured to execute:

a plurality of components for executing application;

a domain profile for storing information on the plurality of components;

an assembly controller for executing the plurality of components; and

a relay component connected to the plurality of components to transmit control information on the assembly controller to the plurality of components and to transmit input data to a predetermined component in accordance with request of one of the plurality of components based on information on the domain profile,

wherein the plurality of components comprise an input port and an output port connected to the relay component,

wherein the relay component comprises a plurality of input ports and a plurality of output ports connected to the plurality of components, and

wherein the input ports and the output ports of the relay component are connected to each other one to one in a single direction.

2. The system of claim 1, wherein, when a destination list for transmitted data is requested by one of the plurality of components, the relay component generates a routing table to transmit data in accordance with information on a component to which the data are to be transmitted.

3. The system of claim 2, the relay component generates the routing table so that the data are transmitted to a plurality of components to correspond to the destination list request.

4. The system of claim 2, wherein the relay component sets an input port connected to a component to which data are to be transmitted as a transmitting unit of data and generates the routing table using output ports connected to components in accordance with the destination list as destination information.

5. A method of connecting components of an SCA-based system, comprising:

a relay component performing connection setups for a plurality of components;

receiving request of data transmission from one of the plurality of components in accordance with the connection setups;

generating a routing table for transmitting units and receiving units of data in accordance with the request; and

when data are received, transmitting data to a component corresponding to the data based on the routing table,

wherein the plurality of components comprise an input port and an output port connected to the relay component,

wherein the relay component comprises a plurality of input ports and a plurality of output ports connected to the plurality of components, and

wherein the input ports and the output ports of the relay component are connected to each other one to one in a single direction.

6. The method of claim 5, wherein generating the routing table further comprises setting an input port of the relay component connected to a component that requested data to be transmitted as a transmitting unit and setting an output port connected to a component that will receive data as destination information.

7. The method of claim 5, wherein performing the connection setups further comprises one to one connecting one of a plurality of input ports included in the relay component to one output port of the plurality of components and one to one connecting one of a plurality of output ports included in the relay component to one input port of one of the plurality of components.

8. The method of claim 7, wherein performing the connection setups further comprises storing information on components connected to a plurality of input ports and output ports of the connection components in a domain profile.
