Abstract
A system is provided for estimating interarrival jitter in real time, using hardware elements. The apparatus is capable of processing orders of magnitude more packetized voice streams than prior art software implementations. According to a preferred embodiment of the invention, a plurality of registers and arithmetic units are used to process packet spacing values to generate an estimate of the packet interarrival jitter. The hardware elements are controlled by a state machine whose operation is initiated by the reception of a packet of voice data.
