Abstract: The present invention relates to a data processing system and method and, more particularly, to a software TDM bus emulator which emulates the operation of a TDM bus. Often computer aided telephony voice processing applications that require specialised processing services such as DTMF tone detection, facsimile service and voice recognition or synthesis services. Typically, these services are provided via dedicated hardware digital signal processors that communicate using a SONET bus. However, not all computer aided telephony servers have the full range of such specialised hardware resources. Accordingly, the present invention provides a data processing method in which a TDM bus is emulated to periodically execute, using system resources, a number of software data processing resources, which communicate with each other to form a data processing chain. The results of the data processing chain are ultimately returned to the voice application.

Abstract: The present invention relates to a data processing system and method and, more particularly, to a TDM resource manager which responds to receiving a request from an application for specified call processing resources, by determining whether or not there exists a time slot of a TDM bus that can be used to access the DSPs resources required to meet the needs of the application. If such a time slot exists, that time slot is reserved for use by the voice application and the voice application executes using appropriate calls to the reserved DSP resources over the reserved time slots.
