Texas Instruments last week bought Telogy Networks in a bid to increase its presence in the converging voice and data markets.
TI paid $435 million (£270 million) for the firm.
Telogy makes software, dubbed Golden Gateway, to send and receive data over IP, frame relay and ATM networks. The software only works with TI's DSP (digital signal processing) chips.
TI is one of the major players in the DSP market, which is expanding with the convergence of voice and data on networks and over the Internet.
The acquisition of Telogy gives TI the decoding software its DSP chips need to offer a more complete package in this market.
