Smartphones represent one of the fastest growing markets, providing significant hardware/software improvements every few months. However, supporting these capabilities reduces the operating time per battery charge. The CPU/GPU component is only left with a shrinking fraction of the power budget, since most of the energy is consumed by the screen and the(More)
Transformation of Mucor circinelloides with plasmid pTL42 led to the identification of different integrative events. Analysis of eight transformed strains allowed the detection of three classes of transformants: integrative types derived from either homologous (exclusively at the leuA locus) or heterologous recombination and a class which originated by gene(More)
Redundancy is at the heart of graphical applications. In fact, generating an animation typically involves the succession of extremely similar images. In terms of rendering these images, this behavior translates into the creation of many fragment programs with the exact same input data. We have measured this fragment redundancy for a set of commercial(More)
Transformation of a Mucor circinelloides Leu- strain with the plasmid pAD45, harbouring the wild-type allele (leuA+) and a chymosin gene, led to the identification of mitotically stable transformants after one to three vegetative growth cycles on non-selective medium. Southern analysis of the stable transformed strains demonstrated that the vector is(More)
In this paper we present TEAPOT, a full system GPU simulator, whose goal is to allow the evaluation of the GPUs that reside in mobile phones and tablets. To this extent, it has a cycle accurate GPU model for evaluating performance, power models for the GPU, the memory subsystem and for OLED screens, and image quality metrics. Unlike prior GPU simulators,(More)
Perhaps one of the most important design aspects for smartphones and tablets is improving their energy efficiency. Unfortunately, rich media content applications typically put significant pressure to the GPU's memory subsystem. In this paper we propose a novel means of dramatically improving the energy efficiency of these devices, for this popular type of(More)
Smartphones are emerging as one of the fastest growing markets, providing enhanced capabilities every few months. However, supporting these hardware/software improvements comes at the cost of reducing the operating time per battery charge. The GPU is only left with a shrinking fraction of the power budget, but the trend towards better screens will(More)
