Patent ID: 6856615

Claim:
An article of manufacture comprising: shared memory; program memory to store a plurality of instructions; a counter to be clocked by a signal derived from a stratum traceable clock (STC) reference; a processor to execute the plurality of instructions stored in the program memory and thereby (1) process voice payload into voice packets for one or more channels, the voice payload having been obtained from a plurality of network packets sent by a sender machine through a network, and (2) buffer the voice packets before writing them to the shared memory, wherein one or more of the buffered voice packets are written by the processor in response to and only if an interrupt is received from the counter; a digital signal processor (DSP) system to read the plurality of voice packets from the shared memory before processing them; and an interface to a bus, to transmit voice data of one or more channels, from the voice packets processed by the DSP system, over the bus and according to a bus clock, wherein the bus clock is derived from the STC reference signal.
