| Abstract: | In the field of telecommunications, especially in the No.7 signa system applications, timers are of crucial significance. With TUP as an example, the timing behavior of a No.7 system as well as the objects served and the requirements of the server are analyzed. Based on UNIX and VMEexec real time operating system platform, the standard UNIX timer services are extended to provide a real time, high resolution timer handling facility. The design scheme, algorithm and performance are also discussed. |
