VoIP Software Leadership

n 1993: D2 Tech founded– HQ: Santa Barbara, CA– Provider of VoIP software for TI

DSP’s: C54x and C55x– Acquired by Virata (became

GlobespanVirata) in 2000

n 2003: New D2 Tech formed– Spun-out of Globespan-Virata– Re-acquired IP portfolio &

customer accounts

n 2004: Taiwan office opened – Provide efficient local integration

and training support for Aisa including JP, TW, CN, KR ..etc

n 10’s of billions mins/month– Leading softswitch vendors– CPE and end-points– Over 14yr+ proven field S/W

n vOpen: Complete VoIP s/w on TI C54x and C55x DSP– Rich voice coder: G.729AB,

G.723.1A, GSM/AMR, ..etc

n vPort: SoftDSP on PowerPC,MIPS, ARM based SOCs– ARM: 920, 922, 926ejs, 11– MIPS: 4K, 4KEc, 24K, 34K, 64– PowerPC SoC: Freescale, AMD.– Others on Demand

Value Position of D2 vPort on Power Architect

�Save the H/W cost of dual CPU, external DSP, extra memory, I/O … etc

�Single toolchain and O/S for development on the same CPU which reduced S/W development cycle

�Simplify the hardware design

11

�Utilize the unused cycles and DSP instructions of high-speed advanced Power Architecture CPU’s. EX: Freescale MPC83xx

�Portable S/W to the same Power Architecture architecture, EX: migrate from MPC8314/8315 to MPC8323

�Best solution for CPE devices
