Cognovo launches LTE soft modem

The Cognovo SDM platform is suitable for handsets and portable devices capable of LTE Category 4 data transmission at 150-Mbps but also scales to support multi-mode operation with other standards, Cognovo said. A single-engine supporting WCDMA, HSPA, HSPA+, LTE and WiMAX enables a multimode baseband IC to be realized in a die area of less than 6 square millimeters in 32-nm geometry - significantly smaller than conventional modem ICs, the company claimed. Cognovo has developed a C compiler and a system design toolkit to support the architecture.

"Our platform for LTE handsets is a ground-up design, not just a re-targeting of a legacy product; and the MCE is more than just a processor, it's a platform solution for SDM," said Gordon Aspin, CEO of Cognovo, in a statement.

"The software and system support that Cognovo has brought to the software-defined modem platform complements the many years of development by ARM of the Ardbeg Vector Signal Processor," said Warren East, CEO of ARM, in the same statement. "We are delighted with the rapid progress made by the Cognovo team and look forward to seeing end products utilising the platform to enhance the user mobile experience."

"The Software Defined Radio concept has been around for a while, but with the move to HSPA and LTE a more flexible approach is becoming essential. Cognovo's combination of disruptive processor technology with a set of supporting software and tools promises to enable handset makers to bring products to market much faster than before and with significant cost savings in the modem; the most critical part of a wireless terminal," said Will Strauss, President of Forward Concepts, in the same statement.

In the same statement Pekka Sarlund, a veteran of the wireless industry, said: "Software Defined Radio has been a long time coming and is only now becoming competitive with conventional techniques. The Cognovo platform has addressed all the concerns of OEMs and I expect their techniques to change the way companies design handsets over the next few years."
