This IDC study examines 2004 vendor shares in the VoIP semiconductor market. As the VoIP-specific semiconductor market (digital signal processors [DSPs], application-specific integrated circuits [ASICs], and application-specific standard products [ASSPs]) grew over 40% in 2004, other vendors have been chipping away at Texas Instrument's (TI's) dominant share position. TI still held onto the number 1 revenue share with its strong DSP offerings, especially in PBX and gateway sockets. Broadcom moved up to the number 2 position, with high growth in its IP phone business. Mindspeed nabbed the number 3 position, with rapid growth in media gateway silicon.

"The migration to more efficient VoIP networks will continue to drive a strong revenue opportunity for semiconductor suppliers that are driving channel integration, software, and lower costs in their reference designs." ? Mario Morales, vice president, Semiconductors research
