Abstract

The new generation of personal interactive mobile multimedia mobile communication (M/sup 3/C) demand highly compact low power devices capable of image capture and display as well as low bit rate coding and transmission. The new design concept based upon integration of optics with that of electronics has facilitated the realisation of a novel intelligent pixel array architecture to create a real-time implementation of forward and inverse wavelet transform for image capture, in-situ processing and display. The processor consists of an array of intelligent pixel (IP) processing elements. Each element of the array incorporates three components: (a) a photodetector with associated analogue to digital converter for the conversion of the incident light; (b) embedded processor for implementation of parallel video codec algorithm; (c) a liquid crystal display for the conversion of the decoded incoming video stream to an optical output for display. To carry out the required video coding the IP array is used to emulate a mesh network of processing elements such that the inherent parallelism and interconnectivity of the architecture is fully exploited.

集成光vlsi移动多媒体通信器

新一代个人交互式移动多媒体移动通信(M/sup / 3/C)要求具有高度紧凑、低功耗的图像采集和显示设备以及低比特率的编码和传输设备。基于光学与电子学集成的新设计理念促进了一种新型智能像素阵列架构的实现，以创建用于图像捕获，原位处理和显示的正、逆小波变换的实时实现。该处理器由一组智能像素(IP)处理元素组成。该阵列的每个元件包含三个组件:(a)光电探测器，其带有用于转换入射光的相关模拟-数字转换器;(b)嵌入式处理器，实现并行视频编解码算法;(c)液晶显示器，用于将解码的输入视频流转换为用于显示的光输出。为了进行所需的视频编码，IP阵列被用来模拟处理元素的网状网络，从而充分利用该体系结构固有的并行性和互连性。
