In modern multimedia applications, memory bottleneck can be alleviated with special stride data accesses. Data elements in stride access can be retrieved in parallel with parallel memories, in which the idea is to increase memory bandwidth with several memory modules working in parallel and feed the processor with only necessary data. Arbitrary stride access capability with interleaved memories is described in previous research where the skewing scheme is changed at run time according to the currently used stride. This paper presents the improved schemes which are adapted to parallel memories. The proposed novel parallel memory implementation allows conflict free accesses with all the constant strides which has not been possible in prior application specific parallel memories. Moreover, the possible access locations are unrestricted and the accessed data element count equals to the number of memory modules. Timing and area estimates are given for Altera Stratix FPGA and 0.18 micrometer CMOS process with memory module count from 2 to 32. The FPGA results show 129 MHz clock frequency for a system with 16 memory modules when read and write latencies are 3 and 2 clock cycles, respectively. The complexity of the proposed system is shown to be a trade-off between application specific and highly configurable parallel memory system.

“…El rango de arquitecturas propuestas para aplicaciones móviles va desde procesadores de aplicación específica, procesadores de propósito general (GPP) con extensiones multimedia (conocidos también como GPP de instrucciones con múltiples datos (SIMD)), 2,3 procesadores multimedia de propósito especial, 4 procesadores superescalares, procesadores tipo VLIW (Very Long Instruction Word) 5 y plataformas completamente reconfigurables. Sin embargo, el rango de arquitecturas que han demostrado ser óptimas para responder acertadamente a las restricciones impuestas por las aplicaciones móviles es más reducido que la clasificación presentada anteriormente.…”

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
