PowerVR PCXl芯片,作为下一代交互式娱乐设备的三维图形处理的主力芯片,近日由NEC和VideoLogic公司联合开发成功。‘97多媒体芯片争斗的序幕已经拉开。 PowerVR PCXl从体系结构上去掉了对Z-buffer存储体的需要,降低了系统造价并消除了Z-buffer的带宽瓶颈问题。它转而采用SGRAM/SDRAM,为PC平台提供一个强大、高效、低成本的3-D图形加速处理器。 PowerVR PCXl chip, as the next generation of interactive entertainment equipment, the main chip of the three-dimensional graphics processing, recently jointly developed by NEC and VideoLogic successfully. ’97 prelude to the battle of multimedia chips has been opened. PowerVR PCXl eliminates the need for Z-buffer memory banks, reduces system cost and eliminates bandwidth bottlenecks in Z-buffers. Instead, it uses SGRAM / SDRAM to provide the PC platform with a powerful, efficient, low-cost 3-D graphics acceleration processor.
