ABI Research asks, How Will Mobile Phone Trends Affect the Handset's Digital Signal Processor?OYSTER BAY, N.Y. -- What changes are coming to the mobile phone, and how will they affect the handset's digital signal processing See DSP. Digital Signal Processing - (DSP) Computer manipulation of analog signals (commonly sound or image) which have been converted to digital form (sampled). ? ABI Abi (ā`bī) [short for Abijah], in the Bible, King Hezekiah's mother. (Application Binary Interface) A specification for a specific hardware platform combined with the operating system. Research has identified four major trends: --Transition of cellular protocols to 3G and 4G standards. Even though the industry is, to date, barely deploying standards such as UMTS (Universal Mobile Telecommunications System) The GSM implementation of the 3G wireless phone system. Part of IMT-2000, UMTS provides service in the 2 GHz band and offers global roaming and personalized features. and EV-DO (EVolution-Data Only) A 3G high-speed digital data service provided by cellular carriers worldwide that use the CDMA technology, including Verizon and Sprint in the U.S. EV-DO works on EV-DO cellphones as well as laptops and portable devices that have EV-DO modems. , demos are already under way for next generation standards that employ OFDM (Orthogonal Frequency Division Multiplexing) A digital transmission technique that uses a large number of carriers spaced apart at slightly different frequencies. and MIMO (Multiple Input/Multiple Output) Pronounced "my-mo," it is the use of multiple transmitters and receivers (multiple antennas) on wireless devices for improved performance. to enable 100Mbit-type data rates. --Advanced multimedia such as video conferencing, 3D gaming and graphics, and mobile TV. Such applications are very computing-intensive. --Wireless connectivity technologies such as Wi-Fi, Bluetooth, GPS, Ultrawideband, and WiMAX. No technology is ideal in all applications, so the holy grail is to support all wireless technologies and protocols. --Efforts to improve link margins and communications quality. With growing penetration of cellular networks worldwide, there is increased focus on improving cellular communications without significantly increasing network Capex and Opex. How will these trends affect the DSP's design? Alan Varghese, ABI Research's principal analyst, semiconductor research, sees two pathways: one evolutionary, the other disruptive and revolutionary. "The evolutionary path," he notes, "involves increasing reliance on hardware accelerators and coprocessors to offload the DSP's work. But this approach might run into problems: it is going to be too complex to support all the hardware required for all the protocols mentioned above. A hardware-centric architecture also precludes quick adaptations to new requirements." ABI Research sees revolutionary promise in a new set of vendors such as Sandbridge Technologies and Morpho morpho Any species of New World tropical brush-footed butterflies in the genus Morpho (family Nymphalidae). Microscopic ridges on the wing scales break up and reflect light, producing the iridescent blue of the males of some species. Technologies, whose software-defined architectures are finally becoming viable in the handset. "Considering that the mobile phone DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive is approximately a $5 billion industry," Varghese concludes, "current market leaders may need to start looking over their shoulders." ABI Research's new study, "DSP in the Mobile Phone - Chipsets, Technologies and Market Drivers" discusses business models, technology trends, forecasts, and many other issues in detail. Founded in 1990 and headquartered in New York, ABI Research maintains global operations supporting annual research programs, intelligence services and market reports in automotive, wireless, semiconductors, broadband, and energy.
