【 摘 要 】

In this paper we focus on algorithms and reconfigurable tiled architectures for streaming DSP applications.The tile concept has a number of advantages: (1) depending onthe requirements more or less tiles can be switched on/off, (2) thetile structure fits well to future IC process technologies, more tileswill be available in advanced process technologies, but thecomplexity per tile stays the same, (3) the tile concept is faulttolerant, faulty tiles can be discarded and (4) tiles can beconfigured in parallel. Because processing and memory iscombined in the tiles, tasks can be executed efficiently (locality ofreference). There are a number of application domains that canbe considered as streaming DSP applications, for examplewireless baseband processing (for HiperLAN/2, WiMax, DAB,DRM, and DVB), multimedia processing (e.g. MPEG, MP3coding/decoding), medical image processing, color imageprocessing, sensor processing (e.g. remote surveillance cameras)and phased array radar systems. In this paper the keycharacteristics of streaming DSP applications are highlighted,and the characteristics of the processing architectures toefficiently support these types of applications are addressed.
