Grandstream chose TI's TMS320C5501 DSP because of its high performance for advanced digital signal processing and affordable cost. The C5501 DSP allows Grandstream to offer superb voice clarity, enhanced security protection for device provisioning and private communications, and all the popular PBX phone features on its GXP2000 enterprise IP phone product, including transfer, forward, do not disturb, hold, mute, 3-way conference, intercom/paging, shared line presence, call park/pick up, speed dial, full duplex hands-free speakerphone, etc, at a much lower price level than competition. Optimized for communication devices, music effectors and portable medical devices, the TMS320C5501 fixed-point DSP is based on the TMS320C55x DSP generation CPU processor core. The C55x DSP architecture achieves high performance and low power through increased parallelism and total focus on reduction in power dissipation.

“We are very excited about working with TI and using their industry leading DSP that powers our innovative VoIP products. By leveraging the powerful processing capabilities, extended features and relatively low cost of TI's DSP, Grandstream is able to design and deliver advanced IP voice and video products with high quality, rich functions at unrivaled price points,” says David Li, CEO of Grandstream Networks, Inc.
