Compared with multicore microprocessors (MPUs) in the server market that dissipate tens of watts, the low-power MSC812x devices deliver an unmatched 2GHz and 8GMACS of DSP processing power while dissipating only 2W.
"Freescale's MSC8122 multicore DSP delivers the performance we need for our next-generation CDMA IP-BSC equipment while enabling us to reduce our cost- and power-per-channel, increase our board density and preserve our software investment", said Mark Borota, Motorola's Senior Vice President of Cellular Networks.
Embedded system developers are now looking at DSPs, such as Freescale's MSC812x family, as alternatives to higher power, general-purpose MPUs.
With four cores running at 500MHz and delivering 2GHz combined performance, these multicore DSPs are ideal for a wide range of computation-intensive infrastructure applications.
Examples include radio network controllers (RNCs), packet telephony media gateways, video multi-conferencing units and high-speed downlink packet access (HSDPA) support for basestations.
The processing power of the MSC812x devices also enables the convergence of software-driven applications by offering video, voice, fax and modem capabilities on a single platform.
"The compression, transcoding and interworking requirements of voice in converged networks have historically been addressed by power-hungry DSP farms", said Sanjay Iyer, Senior Analyst at The Linley Group.
"Freescale's new quad-core MSC8122 and MSC8126 DSPs leverage the advantages of 90nm technology to deliver an unprecedented 8GMACS of signal-processing performance at a low 2W".
"An array of these devices constitutes a programmable, power-efficient DSP platform that can support a variety of demanding applications, such as transcoding gateways and 3G wireless basestations".
"By offering volume production of our multicore programmable DSPs, Freescale is delivering on our promise to provide embedded systems designers with a high-performance, low-power option to general-purpose single-core DSPs and MPUs", said Lynelle McKay, Vice President and General Manager of Freescale's Networking and Communications Systems Division.
"Our customers need greater processing power with low power dissipation at a cost-effective price point".
"The MSC812x devices not only deliver exceptional performance but also offer the benefits of 90nm process technology, which enables low core voltage, lower cost and low power dissipation".
The MSC812x DSPs, recently highlighted in EDN's "Hot Products of 2004", offer 1.43Mbyte of internal memory, a high bandwidth external memory interface, a rich set of advanced peripherals including an 10/100Mbit/s Ethernet controller, and high throughput coprocessors, all on an optimised architecture featuring Freescale's best-in-class, multicore system-on-chip (SoC) platform design.
The MSC8126 device features a turbo-coding coprocessor (TCOP) and Viterbi coprocessor (VCOP) to accelerate wireless baseband processing.
All MSC812x devices are binary software compatible with single-core MSC711xx and MSC81xx families and pin-compatible with the first-generation MSC8102 device.
The 300 and 400MHz versions of the MSC812x DSPs are offered at an extended temperature range of -40 to +105C.
The 500MHz version is offered at standard temperature of 0 to 90C.
As a leader in DSP solutions for wireless and VoIP infrastructure applications, Freescale has shipped multiple millions of DSPs based on StarCore technology since the architecture's inception in 2001.
Freescale has shipped MSC812x DSPs to more than 20 customers designing VoIP and wireless infrastructure applications.
Freescale is the only supplier of programmable DSP solutions with binary code compatibility spanning from four to 8000-plus channels.
The MSC812x devices are designed to exceed customer expectations for high quality, robustness, programmability and availability of a full service development ecosystem.
Freescale offers turnkey software solution with a comprehensive VoIP and wireless transcoding framework.
Freescale offers MSC8122ADS and MSC8126ADS development boards that work seamlessly with the CodeWarrior Development Studio for DSPs based on StarCore technology.
The MSC8122 and MSC8126 devices at 500, 400 and 300MHz have passed full industrial qualification and are now available for volume production.
MSC812x family unit pricing starts at $127.74 in 10,000-unit quantities.
