  9. 9. Outline<br />Communication is what?<br />Talk about “More”<br />Infrastructure<br />Physical Device<br />Device Driver<br />Protocol Implementation<br />Application<br />Modularity<br />Q&A<br />
  10. 10. Communication is what?<br />
  11. 11. Talk about “More”<br /><ul><li>Object orientation
  12. 12. Microkernel design
  13. 13. Client/Server models</li></li></ul><li>Infrastructure<br />
  14. 14. The Physical Device<br />Symbian OS has no control over hardware<br />That is API design.<br />We will treat as an abstract.<br /> Can handle wide variety of devices now and also future.<br />
  15. 15. The Device Driver Layer<br />Logical Device Driver( LDD): Layer interfaces with the protocol implementation layer and Symbian OS policies.<br />Physical Device Driver( PDD): Layer interfaces directly with the physical device through a specific hardware port.<br />
  16. 16. The protocol Implementation Layer<br />Four types of modules:<br />CSY Modules: Communicate directly with the hardware through PDD portion of device driver. Implementing the various low-level aspects of protocol.<br />TSY Modules: Implement the telephony fuctionality.<br />PRT Modules: Central modules used for protocol implementation.<br />MTMs: Handle all type of messaging.<br />
  17. 17. Modularity<br />
