New applications demand very high processing power when run on embedded systems. Very Long Instruction Word (VLIW) architectures have emerged as a promising alternative to provide such processing capabilities under the given energy budget. However, in this ...
This paper presents a thermal model to analyze the temperature evolution in the shared register files found on VLIW systems. The use of this model allows the analysis of several factors that have an strong impact on the heat transfer: layout topology, plac ...
In this paper we introduce a new hardware/software approach to reduce the energy of the shared register file in upcoming embedded architectures with several VLIW processors. This work includes a set of architectural extensions and special loop unrolling te ...
Advancements in imaging technology made commercially available cameras cheaper, easily accessible with higher resolution than ever and with complex image capturing features. Today, it is estimated that more than one billion cameras sold every year. However ...
A conception as well as a CMOS implementation of the analog, ultra low power and fully parallel image processor have been presented in this paper. Proposed circuit bases on the 2-D FIR filters realized using the Gilbert vector multiplier. Proposed filter e ...
The expansion of 3D real-time simulations (3DRTS) into millions of homes together with the technical progress of computers hardware force to approach software developments for 3DRTS from different perspectives. From an historical standpoint, 3DRTS started ...
Research in multimedia for consumer electronics is dominated by the problem of incredibly short times-to-market, that means fast complexity estimations and fast design of new architectures. On one side more and more sophisticated and flexible applications ...
The register file is one of the hottest devices in processor- based systems. Leakage reduction techniques and DTM mechanisms re- quire a thermal characterization of the hardware. This paper presents a thermal model to analyze the temperature evolution in t ...
Process variation in future technologies can cause severe performance degradation since different parts of the shared Register File (RF) in VLIW processors may operate at various speeds. In this paper we present a complete approach that handles speed varia ...
The development of more processing demanding video standards on one hand and the popularity of mobile devices such as digital cameras or wireless videophones on the other hand introduce a need of optimization at the processor level. Reconfigurable systems ...
