Targeting the market's largest segment, the TrueNTRY X122 low-cost cellular-phone platform consists of silicon chips, software (including Agere's proven protocol stack and frameworks) and a development kit. It platform adheres to the General Packet Radio Service (GPRS) cellular standard. This platform enables a wide range of capabilities for entry-level phones, including compact-disc-quality music, camera/camcorder functions and Internet access for a bill-of-materials cost of less that $30. Some of the integrated hardware features that help reduce BOM costs include a speaker amplifier, CD-quality stereo, a polyphonic sound synthesiser, a USB 2.0 On-the-Go controller with charging, power-management circuits to support all phone peripherals and battery-charging circuits with over-voltage protection. By providing a dedicated application processor separate from the communications engine, the platform reduces a cell-phone manufacturer's product-development costs and boosts overall processing speed. The extra processing power means that users can receive phone calls or surf the web while playing music, or reduce overall power consumption when the application processor is turned off. This also eases the development, test and verification of application software as development doesn't impact the core communications engine. The platform supports advanced audio processing including dynamic noise suppression, echo cancellation, full-duplex speakerphone and a stereo equaliser. The X122's analogue baseband integrates GSM/GPRS handset features such as power control, frequency control, analogue baseband processing, audio mixing and conversion, real-time clock and power management.
