Two of the most important design issues for next generation handheld devices are wireless networking and the processing of multimedia content. Both applications rely heavily on computationally intensive digital signal processing algorithms. Programmable architectures that keep pace with the increasing performance requirements become more and more power(More)
Future mobile communication systems have to be flexible while adapting to environmental conditions and user demands. These systems also have to be energy-efficient as they are used in battery-operated terminals. We expect that heterogeneous reconfigurable hardware can overcome the contradicting requirements in flexibility, energy-efficiency and performance.(More)
The availability of high-level design entry tooling is crucial for the viability of any reconfigurable SoC architecture. This paper presents a graph covering algorithm. The graph covering is done in two steps: template generation and template selection. The objective of template generation step is to extract functional equivalent structures, i.e. templates,(More)
Mobile wireless terminals tend to become multimode wireless communication devices. Furthermore, these devices become adaptive. Heterogeneous reconfigurable hardware provides the flexibility, performance, and efficiency to enable the implementation of these devices. The implementation of a wideband code division multiple access and an orthogonal frequency(More)
Dynamically reconfigurable systems offer the potential for realising efficient systems as well as providing adaptability to changing system requirements. Such systems are suitable for future mobile multimedia systems that have limited battery resources, must handle diverse data types, and must operate in dynamic application and communication environments.(More)
Mobile wireless communication systems become multi-mode systems. These future mobile systems employ multiple wireless communication standards, which are different by means of algorithms that are used to implement the baseband processing and the channel decoding. Efficient implementation of multiple wireless standards in mobile terminals requires(More)
Primary requirements of wireless multimedia handheld computers are high-performance, flexibility, energy-efficiency and low costs. A compromise for these contradicting requirements can be found in a heterogeneous SoC. Besides conventional architectures such a SoC contains domain specific coarse grain reconfigurable processors and fine-grain reconfigurable(More)
