3. 2. Design of programmable multi-standard baseband processors

   Författare :Anders Nilsson; Dake Liu; Gerhard Fettweis; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DSP; baseband processor; ASIP; Computer engineering; Datorteknik;

   Sammanfattning : Efficient programmable baseband processors are important to enable true multi-standard radio platforms as convergence of mobile communication devices and systems requires multi-standard processing devices. The processors do not only need the capability to handle differences in a single standard, often there is a great need to cover several completely different modulation methods such as OFDM and CDMA with the same processing device.

4. 3. Dynamically Reconfigurable Architectures for Real-time Baseband Processing

   Författare :Chenxin Zhang; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reconfigurable Computing; Coarse-Grained Architecture; Dynamic Reconfiguration; SIMD; VLIW; ASIP; Vector Processor; Baseband Processing; OFDM; MIMO; Channel Estimation; Symbol Detection.;

   Sammanfattning : Motivated by challenges from today's fast-evolving wireless communication standards and soaring silicon design cost, it is important to design a flexible hardware platform that can be dynamically reconfigured to adapt to current operating scenarios, provide seamless handover between different communication networks, and extend the longevity of advanced systems. Moreover, increasingly sophisticated baseband processing algorithms pose stringent requirements of real-time processing for hardware implementations, especially for power-budget limited mobile terminals.

5. 4. ASIP for Wireless Communication and Media

   Författare :Johan Eilert; Dake Liu; Viktor Öwall; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : While general purpose processors reach both high performance and high application flexibility, this comes at a high cost in terms of silicon area and power consumption. In systems where high application flexibility is not required, it is possible to trade off flexibility for lower cost by tailoring the processor to the application to create an Application Specific Instruction set Processor (ASIP) with high performance yet low silicon cost.

7. 5. Design of Energy-Efficient High-Performance ASIP-DSP Platforms

   Författare :Andréas Karlsson; Dake Liu; Andreas Ehliar; Jarmo Takala; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In the last ten years, limited clock frequency scaling and increasing power density has shifted IC design focus towards parallelism, heterogeneity and energy efficiency. Improving energy efficiency is by no means simple and it calls for a reevaluation of old design choices in processor architecture, and perhaps more importantly, development of new programming methodologies that exploit the features of modern architectures.
