Program-controlled communications system

Abstract

Abstract A program-controlled communication system consists of, among other things, a digital computing system with a computer core (processor) managed by a multi-tasking operating system and a system memory in which a multiplicity of program modules (PM 2) is stored. Each of the program modules is used for implementing a particular function of the communication system. A function can only be executed by the relevant program module being processed by the computer core. Since, as a rule, several functions are ready to be executed, the program modules ready for execution are noted in a process list (PL) from which the operating system (Bs) in each case selects the program module having the highest priority (Pr) and allocates it to the computer core for execution. To be able to prevent a prolonged displacement of program modules with low priority, the program modules are combined in groups (so-called program module function classes (Kl)) which are successively in each case assessed to be current for a certain time in periodic sequence, the operating system, when selecting from the process list, in each case only taking into consideration those program modules which belong to the program module function class which is current in each case. <IMAGE>
