LONDON IPFlex Inc., a Japanese developer of a reconfigurable paralleling processing platform in the form of its DAPDNA-2 chip, has teamed up with Sobal Corp. to offer a codeveloped FFT development kit. The FFT/inverse FFT library in the kit was developed by Sobal.
Sobal is a Japanese R&D specialist with a background in wireless technology and digital consumer product development. Sobal expects to boost its growth in wireless applications by developing boards and consumer systems around the DAPDNA-2 dynamically reconfigurable processor.
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.
The kit includes libraries necessary for dynamically switching between
16-bit Fast Fourier Transforms (FFTs) and inverse FFTs. Optimal
DNA configurations, tuned for processing speed, are provided. User-specific algorithms can be run on the DAPDNA-EB4 evaluation board also included in the kit.
The DAPDNA dynamically reconfigurable processor can change its hardware configuration to provide the circuitry to run 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, IPFlex claimed.
The DAP (Digital Application Processor) refers to a RISC core, while the DNA (Distributed Network Architecture) is a two dimensional matrix of 376 process elements running at 166-MHz clock frequency. Fujitsu fabbed the DAPDNA-2 for IPFlex in March 2004.
