Miniature Sip for Embedded Systems
نویسندگان
چکیده
Session Initiation Protocol (SIP) is an application layer protocol responsible for creating, modifying, and terminating a session. It is used to establish calls through networks via IP protocol. Nowadays, SIP has been used by many embedded systems, however, due to its large size, some constrained systems cannot use it. This paper aims at adapting the protocol to be used in resource-constrained embedded systems, like household appliances and low cost surveillance cameras. In order to achieve this objective, many requests and header fields were suppressed, without compromising its functionalities, resulting in a reduced SIP. The reduced version was implemented in an embedded operating system, reaching a final system image of 116 Kbytes.

Previously, we developed a high-density assembly technology to miniaturize the motion control CPU SiP for humanoid robots. It is necessary to mount a number of passive components on an expensive buildup PWB to accomplish this CPU SiP assembly and satisfy electrical performance requirements. As a result, we developed an embedded device technology to realize further miniaturization and achieve ex...
