After entering the academic field, Professor An-Yeu (Andy) Wu has been taking VLSI signal processing as the main research topic of his lab, and the research results are mainly applied to broadband communication IC design. Latest notable achievements are summarized as follows:

ˇ@

  1.Algorithm-based Low-power Design:

This study was the main subject of Prof. Wuˇ¦s doctoral thesis. The research series was not only published as many IEEE full-length journals, but also invited to be organized as a 48-page journal paper and published as Special Issue on ˇ§Multimedia Signal Processingˇ¨ in Proceedings of IEEE in 1998.

 

  2. Unified Vector Rotational CORDIC Family using ˇ§Angle Quantizationˇ¨ Perspective:

In the series of studies, Prof. Wu first proposed the idea of ˇ§Angle Quantizationˇ¨, AQ. Like Signed Power-of-Two (SPT) method can reduce the hardware cost of digital filters, AQ achieves lower computational complexity by using only several shift-and-add operations to meet the target angle. He re-examined the rotation algorithm of CORDIC (Coordinate Rotational Digital Computer) by the concept of AQ, and then proposed a brand-new design framework that could handle all vector rotations. Prof. Wuˇ¦s team derived a number of new computing algorithms and rotating structures, and published many IEEE full-length journals. In addition, the study of new rotation algorithms also received accreditation praise, such as

-          Paper on MVR-CORDIC was awarded ˇ§Prof. Shen Wenren Memorial Paper Awardˇ¨ in 2002.

-          Paper on EEAS-CORDIC was awarded ˇ§The Best Paper Award Nominationˇ¨ of the 2nd IEEE Asia-Pacific Conference on ASICs (AP-ASIC) in 2000.

3.Reconfigurable Communication Silicon IP Designs:

 

Reconfigurable Design has become a new VLSI design, which combines the efficiency and low-power of ASIC and flexibility of general-purpose processors. In recent years, the research team has researched all kinds of Reconfigurable Communication Silicon Intellectual Property (SIP), including
• Reconfigurable / multi-mode Reed Solomon Codec
• Dual-mode Turbo / Viterbi decoder for 3GPP
• Variable-length FFT Processor for OFDM-based Communication Systems


Part of the design results have been published in journals and international conference papers. Besides, these designs receive excellent awards from ˇ§Silicon Intellectual Property Design Contest" and "National Chip Implementation Center Excellent Chip Design.ˇ¨

 

4. Novel Adaptive Equal Design for Communication / Storage Systems:

 

Equalizer is the core technology for communications and storage systems. We must to considerate the speed of computing (such as 8 ns data rate in Gigabit Ethernet) and the complexity of computing (such as Echo Canceller in xDSL Systems) for equalizer design. In order to meet the requirements of system performance and lower cost chips. The research team has designed a lot of high efficiency and low complexity of the equalizer algorithms and architecture. The designs have published several papers in IEEE journals. And these can be used in the design of communications IC design, such as gigabit Ethernet receiver, HDSL, SDSL and SHDSL system.
