POWERVR SGX543 the first POWERVR Series5XT architecture IP core
The four pipeline POWERVR SGX543 is the first in a series of new SGX IP cores that utilise the POWERVR Series5XT architecture, which delivers significant enhancements to the Series5 SGX architecture used in previous SGX IP cores. SGX543's wide-ranging architectural enhancements include:
* USSE2 - extended USSE instruction set with comprehensive vector operations and co-issue capability
* upgraded tile handling to further reduce memory bandwidth and improve performance for setup-bound applications
* typically 40% faster performance for 'shader-heavy' applications
* 2x floating point and 2x hidden surface removal performance
* enhanced triangle setup delivering up to 50% higher throughput
* improved multi-sampling anti-aliasing performance
* features for optimised performance when used with POWERVR VXD and VXE video cores
* advanced colour space handling and gamma correction
* further optimised OpenVG 1.x support
* cache and MMU improvements
The new POWERVR SGX543 delivers real-world performance of 35 million polygons/sec and 1 Gpixels/sec fillrate at 200MHz,* capable of driving HD screens with ultra smooth high definition 3D graphics. Even in a single-core solution POWERVR SGX543's performance is unprecedented in any GPU, demonstrating Imagination's pace of innovation and ability to drive the consumer experience in graphics to levels unheard of only a few years ago in anything less than high end specialist platforms.作者: elisha 时间: 2010-6-18 12:38
随着时间的推移,PSP游戏机的Media Engine已经不能适应时代对显卡性能的需求,这款显卡不仅3D性能有限,而且还不具备硬解高清视频的功能,为此,索尼自去年起便开始为PSP2物色新的显示核心,去年11月24日,Imagination Technologies公司曾发布了一则新闻公告,公告称他们与一家"大型消费电子厂商"签订了合作协议,将为这家公司的产品提供POWERVR SGX显卡.
