LONDON Design house Blue Wonder Communications (Dresden, Germany), which specializes in baseband chips and IP for mobile broadband applications such as LTE, is to use Tensilica's Xtensa dataplane processors for an LTE broadband modem design.
The German group which said last week it is partnering on the development of an LTE reference design with Lime Microsystems (Guildford, England) using Lime's single chip LTE transceiver alongside its baseband has taken a license on Tensilica's Xtensa processor.
"New design approaches are needed to successfully implement the LTE and LTE Advanced standards," said Dr. Peter Meyer, managing director and head of development at Blue Wonder Communications.
Meyer stressed the traditional approach of using hardwired logic for the performance-intensive PHY layer datapath simply won't work. Because LTE systems run at such high data rates, it would require millions of gates of logic developed with RTL methods - and that creates a huge verification hurdle.
"Using Tensilica's automated processor creation tools we are able to quickly generate customized DPUs delivering the performance levels of custom hardware with the programmability of a processor," added Meyer.
Tensilica offers a variety of options for baseband communications designs, including, for software-centric architectures, optimized DSP architectures under the ConnX DSP family label, including the recently announced ConnX Baseband Engine.
However, for designs with a more hardware-centric approach, such as Blue Wonder's latest basebands, customizable dataplane processors are the ideal building block, Steve Roddy, vice president of marketing at Tensilica told EE Times .
"They do not need a complete dataplane processor unit, but rather optimized functional blocks with the performance equivalent to hardwired logic pared with the flexibility of programmable processors."
Mahesh Venkatraman, Tensilica's vice president of marketing, vertical segments, added: "Blue Wonder Communication's design team fully realizes the benefits of customizing Tensilica's DPUs to meet the requirements of LTE and LTE Advanced handset designs, with requirements for 20-to-150-times the efficiency on a much lower power budget than current 3G designs."
