“…The reasoning behind this large difference is that only PXA270 among the three processors has Intel Wireless MMXTM technology unit [3]. The Wireless MMXTM technology unit internally has an enhanced Multiply and Accumulate Unit (MAU) performing all multiplication and accumulation operations [5]. Since the Fourier coefficients test is comprised of both multiplications and accumulations, we can expect significant performance improvement of PXA270 over both SA 110 and PXA255 in Fourier coefficient test.…”

This paper describes a performance comparison of three well-known embedded mobile processors, Intel SA1110, Intel PXA255, and Intel PXA270. Even though these processors are widely used in commercial handheld devices and consecutively developed in order to improve processing capability, there has been a lack of experimental study investigating their comparative performance. We present here the results of an experimental study into performance comparison based on Linux BYTEmark benchmark suit. The benchmark results show that PXA255 has a significant performance improvement, especially in floating-point operations compared with the other two processors.

The increase of the wireless networks has created a significant growth in demand for portable devices with different types of services such as text processing, connectivity to different networks, remote data base access and multimedia processing. In order to respond to these requirements, a number of different hardware architectures have been proposed recently, designed principally to integrate useful characteristics such as high performance for multimedia functions, energy efficient handling, small size and a low complexity. This work presents a general analysis of several architectures designed principally for real time multimedia processing in mobile applications. This article describes the advantages of these architectures and raises comparison strategy among them. KEY WORDSMobile Computing, real time multimedia processing, power management, multimedia applications. RESUMENEl incremento de las redes inalám-bricas ha creado un significativo incremento en la demanda de dispositivos portátiles que integran diferentes tipos de servicios tales como procesamiento de texto, acceso a bases de datos remotas y procesamiento

Visual Sensor Networks (VSNs) enable enhanced three-dimensional sensing of spaces and objects, and facilitate collaborative reasoning to open up a new realm of vision-based distributed smart applications including security/surveillance, healthcare delivery, traffic monitoring, just to name a few. However, such applications require sensor nodes that can efficiently process large volumes of visual information in-situ and exhibit intelligent behavior to support autonomous operation, scalability, and energy efficiency. This paper presents WASP, a vision sensor node prototype with high computational capabilities that satisfy key VSN application requirements. The node integrates hardware components comprising a generic processor, a wireless communication module, and a camera, with a software framework designed to carry out key visual information processing tasks including object detection, segmentation, and morphological operators for image enhancement. In addition, the framework implements classifiers for target recognition and scenario analysis.
