Share Article

IPFlex Inc. and Sobal Corporation announced today that they have started to ship FFT Development Kit for DAPDNA-2, jointly developed by the two companies. The FFT/IFFT library in the kit was developed by Sobal. Sobal has also joined IPFlex’s DAPDNA* Partner Program. Sobal, with its expertise in the wireless communication and digital consumer fields where FFT/IFFT calculations are used frequently, plans to support customers developing DAPDNA-powered products FFT Development Kit is expected to farther enhance the development environment for DAPDNA-2 and shortens time-to-market for DAPDNA-based systems.

IPFlex Inc. and Sobal Corporation announced today that they have started to ship FFT Development Kit for DAPDNA-2, jointly developed by the two companies. The FFT/IFFT library in the kit was developed by Sobal.

Sobal is a software and hardware R&D specialist with a strong track record in wireless technology and digital consumer product development. In the wireless field, Sobal has been engaged in many R&D activities. These activities include: R&D on a short-range wireless technology that is essential for ubiquitous computing; system solutions utilizing RFID systems; next-generation communications technology using visible frequencies, and so on. Sobal combines software expertise with an advanced R&D capabilities on antennas.  Sobal’s unique value is recognized within the wireless industry where the lack of expertise in combining antenna technology and software technology constituted an obstacle to wireless system introduction. By joining the DAPDNA Partner Program, Sobal expects to further boost growth in wireless applications by developing boards and customer systems using the DAPDNA-2** dynamically reconfigurable processor (DRP)***.

The FFT development kit is the first product that the two companies have jointly developed since Sobal joined the DAPDNA Partner Program. Using the kit, users can extract unprecedented performance such as high processing performance, flexibility, and scalability out of DAPDNA-2 easily, leading to a fast time-to-market. The two companies plan to provide product development and design contracting services to aid users develop systems that take advantage of the performance of DAPDNA processors.

About the FFT Development Kit

The kit includes libraries necessary for dynamically switching between 16 bit Fast Fourier Transforms (FFTs) and inverse FFTs (IFFTs). Optimal DNA configurations, tuned for processing speed, are provided. User-specific algorithms can be run on the DAPDNA-EB4 evaluation board, which has DAPDNA-2 processor, also included in the kit.

About the DAPDNA Partner Program

IPFlex started the partner program in March, 2005, and 15 partners now serve customers in Japan and North America. The goal of the DAPDNA Partner program is for IPFlex and program members to offer unprecedented value to customers in various application areas by leveraging DAPDNA architecture. IPFlex and its DAPDNA partners combine their strengths to deliver optimal solutions to customers for their application development needs.

About the DAPDNA Dynamically Reconfigurable Processor

DAPDNA dynamically reconfigurable processor can change its hardware configuration to provide the optimal circuitry for an application on demand. This configuration change can take place not only when the system is designed, but also during operation, dynamically, in a single clock cycle***, to meet the instantaneous change in needs of applications implemented by the system.


  • DAPDNA: Digital Application Processor based on Distributed Network Architecture.

** DAPDNA-2: Product name of a dynamically reconfigurable processor from IPFlex.

*** Dynamically Reconfigurable Processor: A processor capable of changing chip circuitry dynamically.

**** a single clock cycle: One clock switching operation is possible by creating configuration information beforehand and storing in the background configuration banks.
