Description: Wavelets have widely been used in many signal and image processing applications. In this paper, a new
serial-parallel architecture for wavelet-based image compression is introduced. It is based on a 4-tap wavelet
transform, which is realised using some FIFO memory modules implementing a pixel-level pipeline
architecture to compress and decompress images. The real filter calculation over 4 · 4 window blocks is
done using a tree of carry save adders to ensure the high speed processing required for many applications.
The details of implementing both compressor and decompressor sub-systems are given. The primarily analysis
reveals that the proposed architecture, implemented using current VLSI technologies, can process a
video stream in real time.-Wavelets have been widely used in many sign al and image processing applications. In this p aper. a new serial-parallel architecture for wavele t-based image compression is introduced.

Description: 本文介绍了基于DSP/BIOS实时内核的TIDSP应用程序参考框架RF5。另外,面对目前越来越多的多处理器系统设计以及典型的GPP-DSP架构,本文提出了一种改进的DSP应用程序框架ERF5以最大化地支持这种架构。ERF5主要从GPP-DSP有效通信、任务线程的高效执行与调度以及任务线程颗粒度的合理化三个方面对RF5进行了改进,并已成功应用于实际项目。-In this paper, based on the DSP/BIOS real-time applications TIDSP core frame of reference RF5. In addition, the face of the growing number of multi-processor system design, as well as typical GPP-DSP architecture, this paper proposes an improved framework for DSP applications ERF5 to maximize support for this architecture. ERF5 mainly from the GPP-DSP effective communication, efficient implementation of task-thread tasks threads and scheduling, as well as particle size of the three aspects of the rationalization of RF5 improved, and has been successfully applied in practical projects.
