Processor enables flexible
3G basestation design
Analog Devices has collaborated with Ericsson to develop a programmable baseband platform based on the TigerSHARC processor for WCDMA basestations
The Ericsson basestations leverage the programmability and unique memory structure of the TigerSHARC ADSP-TS201 processor to deliver telecommunications service providers systems that are lower in cost, scalable in capacity, and enable the rapid deployment of new features and media-rich content in a mobile environment.
The TigerSHARC processor design-in demonstrates the commitment of Analog Devices, a supplier to Ericsson of analogue semiconductors, to leverage its signal processing expertise - both analogue and digital - to help customers develop best-in-class products, according to Jerald G Fishman, President and Chief Executive Officer of Analog Devices: "Ericsson's incorporation of the TigerSHARC processor in its cellular basestation technology is one proof point supporting our objective to offer our customers a constantly growing menu of industry-leading technology options".
"This important design win represents the next phase in what we expect will be a strong and enduring collaboration with Ericsson", said Fishman.
Unlike conventional basestations that rely on custom ASICs to perform chip-rate baseband processing, the TigerSHARC processor's programmable architecture enables Ericsson to create a full software-defined baseband processing implementation for wideband-code division multiple access (WCDMA) and to easily add new features as they emerge.
Furthermore, by investing in an all-software solution today, Ericsson will be able to leverage this software investment in future basestation designs with dramatically reduced engineering effort.
The TigerSHARC processor's programmability additionally guarantees rapid compliance with standards such as High-Speed Downlink Packet Access (HSDPA), which is a WCDMA specification that dramatically increases basestation-to-mobile handset downlink speeds in 3G wireless systems.
In a handset, for example, HSDPA-compliant networks allow users to access packet-based multimedia content at up to 14Mbit/s - which is five times faster than existing technology.
The result is that consumers switching to emerging 3G mobile phone service will experience a marked improvement in their ability to access a range of multimedia content.
In addition, because the TigerSHARC-enabled software baseband processing technology promotes scalable 3G system architectures, it allows wireless infrastructure equipment developers to configure basestations to serve a local office, an office complex or an entire wireless cell site.
