Dual-core processor for portable data terminals
Delivering critical technology to the portable data terminals market, Texas Instruments has released the OMAP5912 processor, a heterogeneous digital signal processor plus ARM device.
Budget intro to OMAP-based design
The OMAP5912 Starter Kit (OSK) is intended to smooth the way for the rapid adoption of ARM-plus-DSP SoC technology in the portable data terminal (PDT) market.
As part of the collaboration, QNX is providing a board support package (BSP) that combines the reliability and scalability of QNX Neutrino RTOS with the high processing performance and low power consumption capabilities of TI's OMAP5912 platform which incorporates a TMS320C55xT DSP core and an ARM926EJ-S ARM core.
"The QNX Neutrino RTOS and TI OMAP platform offer features that are highly complementary, resulting in an integrated solution optimised for advanced radio systems that will change the way drivers and passengers access and listen to music and other infotainment applications", said Curt Moore, Manager of Digital Radio and Infotainment, TI.
"The OMAP architecture excels at processing audio content while concurrent processing is going on thanks to its dual core, while QNX delivers a reliable, real-time platform that can handle the performance requirements of next-generation car radios".

TI adds low-cost and high-integration DSP pair
Texas Instruments has unveiled the latest pair of programmable DSPs in its ultra-power-efficient TMS320C55x family of digital signal processors.
Until now, the critical requirements that must be met for high-performance audio systems have not been adequately addressed.
Power management for in-car devices like radio is highly complex and can vary from vehicle to vehicle.
For instance, a device may need to deliver predictable response times while in low-power states, fine-tune power consumption in response to vehicle-specific events or maintain operational readiness for days, or even weeks, after the ignition has been turned off.
Both QNX Neutrino and the OMAP platform deliver power management capabilities that ensure precise, fine-grained control over the power consumption of each system component.
Whether high-end or low-end, in-car audio systems must operate within ultralow power budgets, in which the combined draw of all devices cannot exceed several milliamps or, in some cases, microamps.
TI's power-efficient OMAP processor ensures further extended battery life.
Developers can boost overall application performance on OMAP through the low-power, real-time signal processing capabilities of a DSP coupled with the command and control functionality of an ARM processor.
"Radios are a basic feature in every vehicle that rolls off the factory belt".
"Given the pace of technological developments in the last few years, there's no reason why the average consumer cannot have advanced audio systems in their car that go well beyond just listening to music", said Dan Dodge, CEO of QNX Software Systems.
"Together, QNX and TI are offering the most advanced platform for OEMs to build next-generation audio systems that make music, maps and other infotainment content more portable, storable and accessible than ever".
The QNX BSP for OMAP5912 is expected to be available in November 2004.
