London, 22 January 2002, - RadioScape®, a leading developer of licensable software solutions for the wireless and digital communications markets, announced today the acquisition of the business and assets of Systolix Ltd., a UK-based company that specialises in the development and licensing of digital signal processing solutions based around its PulseDSP™ processor array architecture.

RadioScape will use Systolix's DSP expertise to expand its licensable intellectual property portfolio for Layer-1 wireless baseband development. RadioScape's focus on solving Layer-1 design and development complexity issues resulted in the creation of its licensable hardware abstraction and scheduling software kernel, the Communication Virtual Machine™(CVM®). The CVM allows developers to manage the complexity of wireless systems development by abstracting Layer-1 software production from the underlying hardware resulting in shortened development cycles and increased design success.

The integration of the PulseDSP into the RadioScape portfolio addresses the increasing need for targeted programmable parallelism (TPP) which emerges with next generation and multimode wireless devices (eg. GSM/W-CDMA). RadioScape's CVM will allow the full potential of this parallelism to be exploited in cost and power efficient architectures.

Gavin Ferris, chief technical officer of RadioScape Ltd. said, "The fundamental problem facing Layer-1 developers for wireless systems is the increasing computational complexity of next generation, data-centric, wireless standards combined with the constraints that real-time applications place on these systems. With the CVM we have solved the complexity management issues. PulseDSP gives us the ability to address the programmable, efficient hardware performance that these Layer-1 systems need.

Peter Florence, managing director of RadioScape, Ltd. said, "Systolix's PulseDSP represents a radical new approach to implementing programmable signal processing functions and this technology is a perfect fit for extending RadioScape's portfolio of solutions available to Layer-1 developers for the wireless market. By combining PulseDSP with RadioScape's Communication Virtual Machine™(CVM®) and W-CDMA/UMTS solutions, we offer our customers the most powerful solutions for their wireless development projects." Florence continued, "offices will be maintained in Liverpool and all engineering and support staff have been retained."
