Dynamic Reconfiguration in Mobile Systems

Abstract

Dynamically reconfigurable systems have the potential of realising efficient systems as well as providing adaptability to changing system requirements. Such systems are suitable for future mobile multimedia systems that have limited battery resources, must handle diverse data types, and must operate in dynamic application and communication environments. We propose an approach in which reconfiguration is applied dynamically at various levels of a mobile system, whereas traditionally, reconfigurable systems mainly focus at the gate level only. The research performed in the CHAMELEON project 1 aims at designing such a heterogeneous reconfigurable mobile system. The two main motivations for the system are 1) to have an energy-efficient system, while 2) achieving an adequate Quality of Service for applications.

A Survey on Dynamically Reconfigurable Processors

“…By using customized clustered structure, it achieves better performance than DAPDNA-2 in several tasks for wireless LAN. A RAKE receiver [38] and OFDM receiver [39] have been implemented using coarse grain dynamically reconfigurable processors. An adaptive Viterbi-decoder [40] was implemented on DRP-1 that can change its structure depending on the S/N (Signal/Noise) ratio to optimize the power consumption.…”

Design and implementation of real-time signal processing applications on heterogeneous multiprocessor arrays

“…In this approach, the FPGA is employed as a coprocessor to speed up computationally intensive loops, and the configurable logic fabric in the FPGA is used to support combinational circuits. In [9,4], another kind of heterogeneous platform is targeted. This type of platform consists of a processor, bit-level reconfigurable part (FPGA), and word-level reconfigurable part, called Field Programmable Function Array (FPFA) tiles.…”

Performance and power analysis of time-multiplexed execution on dynamically reconfigurable processor

“…In recent years, dynamically reconfigurable devices have attracted much attention because of their high-speed processing and flexible properties in embedded systems [11] [3]. Recent dynamically reconfigurable processors, such as DRP [7], DAPDNA [4], XPP [8], and D-Fabrix [1], consist of coarse-grained processing elements (PEs) and distributed memory modules.…”
