ABSTRACT:
A method and apparatus for providing multi-channel telephony multimedia services. A multi-tasking DSP processes a plurality of multimedia services for a plurality of telephone channels. The DSP operates in conjunction with a host processor. The host processor indicates to the DSP, in real-time, the services required for a channel. The DSP in response allocates a portion of its fast memory in which a program is stored comprising the multimedia services routines required for the channel. The multimedia services program stored in the portion of fast memory allocated to a channel is then utilized to process the incoming channel signal data. The processed signal data is then output to memory shared between the DSP and the host processor. The portion of memory and the program for each channel can be dynamically reconfigured in real-time on a per channel basis.
