Abstract
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.

Como se muestra en la Figura 3, específicamente la familia PXA27x, integra un core XScale de Intel como módulo CPU, una memoria SRAM on-chip de 256KB la cual es usada como frame buffer para aplicaciones gráficas y de video, diversos módulos multimedia y diferentes interfaces de periféricos (e.g. UART, USB, AC97)
Como trabajo futuro se buscará establecer metodologías que permitan medir el consumo de energía en arquitecturas embebidas orientadas a aplicaciones multimedia móviles, realizando pruebas reales con un conjunto de aplicaciones con los procesadores Dragonball MC9328MX21 de Freescale y PXA270 de Intel, con el fin de establecer medidas comparativas confiables que soporten criterios de selección frente al consumo de potencia, el costo y el desempeño
