基于图形处理芯片的人-机交互系统设计

Design of Human-computer Interaction System Based on Graphic Processor Unit

随着我国经济社会的迅猛发展,人们的精神压力越来越大,为了有效地缓解人们的压力,现代以休闲娱乐为主要目的的人-机交互式系统层出不穷,但大多都以计算机系统为支撑,用软件模拟硬件功能,以牺牲计算机性能为代价的软件系统仍然无法满足人们对混合立体声和高品质视频图像输出的追求。本系统采用多媒体处理芯片PKM32AG-Q,扩展512M显卡内存,可以有效地弥补上述缺点,本文主要介绍人-机交互系统的硬件选择和电路设计,具有一定的应用基础。

With the rapid development of our society economy,people＇s psychological pressure became bigger and bigger,in order to eliminate their mental distress,there have lots of entertainment system,but most of them are based on computer system instead of hardware architect,although with the value of sacrificed computer performance cannot satisfy the desire of high performance of mixer-sound and high quality video output.This system applied multi-medium processor unit PKM32AG-Q and extension of 512M texture memory,so it could compensate the former default.This paper mainly discussed the selection and circuit design of the system,so it has certain application value.
