多媒体计算机需要快速实时完成视频、音频信息的压缩和解压缩、图像的特技效果(改变比例尺、淡入淡出,马赛克)、图形处理(图形的生成和绘制)、语音信息处理(抑制噪音,滤波)等工作,要满意地完成以上任务,一定要用专用芯片。半导体厂商已清楚地看到了这点,他们纷纷参与这一竞争。多媒体计算机专用芯片可归纳为两种类型:一种是固定功能的芯片;一种是可编程的处理器。第一批 Multimedia computers need fast and real-time compression and decompression of video and audio information, special effects of images (changing scale, fade, mosaic), graphics processing (generation and rendering of graphics), processing of voice information (suppression of noise and filtering) , To satisfactorily accomplish the above tasks, we must use a dedicated chip. Semiconductor manufacturers have clearly seen this point, they have to participate in this competition. Multimedia computer chips can be divided into two types: one is a fixed-function chip; one is a programmable processor. The first batch
