Low power real-time programmable DSP development platform for digital hearing aids

This paper presents a new low power binaural wearable digital hearing aid platform based on the Texas Instruments TMS320C5000 fixed point digital signal processor. This platform is a real-time system capable of processing two input speech channels at a 32 kHz sampling rate for each channel and driving a stereo headphone output. It provides for frequency shaping, suppression, multiband amplitude compression, frequency dependent interaural time delay algorithms. Since the platform is a programmable solution capable of running at 1.8 V for MIPS intensive research and 1 V for actual hearing aid implementation, this platform will enable further research into improving the quality of life for the hearing impaired.

EP1: Antiques from the innovations attic

When you clean up your attic you may find things that you have totally forgotten about: old toys you used to play with, old books with lost stories. And then you think back to those past days and view them in the context of todays busy life, and sometimes find new uses for forgotten items.

F2: Reconfigurable RF and data converters

Digital cellular standards have emerged over the last 20 years. Today, 2G systems like GSM/EDGE are providing worldwide coverage for voice and basic data services. The increasing demand of about 4 billon users has led to high demand for low cost multi-standard, multi-mode and multi-band terminals. RF integration using reconfigurable circuits is a key technology to achieve the required technical performance as well as the even more important cost position. Another important commercial aspect of mobile communication systems is the efficient usage of the available spectrum by cognitive radio techniques. The key for this view of cognitive radio is a reconfigurable RF frontend providing the required flexibility. Therefore the wireless forum will investigate the current status and R&D trends in reconfigurable systems focusing on non-4G based reconfigurable RF and reconfigurable data converters. Target systems include cognitive radio and multi-mode/multi-standard systems including short range systems like Bluetooth and WLAN. The forum will cover reconfigurable RF front-ends, their corresponding reconfigurable A/D converters as well as performance on demand concepts and adaptive power consumption.
