SB一个,并行计算非常简单,100CORE的TIEARA知道吗作者: PRAM 时间: 2011-1-6 12:26
Scientists at the University of Glasgow have created a 1,000-core computer processor based on a Xilinx field programmable gate array.
The researchers created 1,000 mini-circuits within the FPGA chip with each core working on its own instructions. The researchers then used the chip to process an algorithm which is central to MPEG decoding and was able to throughput data at a speed of five gigabytes per second: around 20 times faster than current top-end desktop computers.
Wim Vanderbauwhede of the University of Glasgow worked with colleagues at the University of Massachusetts Lowell on the project. The key to the speed up achieved was to give each core its own dedicated memory.
"FPGAs are not used within standard computers because they are fairly difficult to program, but their processing power is huge while their energy consumption is very small because they are so much quicker – so they are also a greener option," said Vanderbauwhede, in a statement.
Vanderbauwhede, is due to present his research at the International Symposium on Applied Reconfigurable Computing in Belfast, Northern Ireland, in March 2011. 作者: PRAM 时间: 2011-1-6 12:26
并行计算都不知道的SB,好意思YY作者: PRAM 时间: 2011-1-6 12:27 作者: PRAM 时间: 2011-1-6 12:27 本帖最后由 PRAM 于 2011-1-6 12:31 编辑
原来U5400什么的都不是低功耗啊.
你不会天真地以为sandy bridge没低功耗吧?
到了Huron River时代,封装尺寸将进一步缩小。据悉PGA封装版处理器尺寸将仍为37.5x37.5mm,而BGA封装版由于将CPU和GPU融合,封装尺寸将缩小到31x24mm。处理器功耗和上代产品保持一致,分别为标准版55W、45W、35W,LV低电压版25W,ULV超低电压版18W。不过,在Calpella平台中45W TDP的四核处理器只有PGA封装版,Huron River则将提供BGA封装版,轻薄本有望用上四核心。
Though it depends on the particular test, the HD 4225 usually falls just under the GMA HD and just above the HD 3200 in the graphics-intensive benchmarks. The 3DMark showed that the values for version 3, 5 or 6 are each around 12-13% better on the Dell Inspiron M101z with the same CPU and GPU. The Dell notebook was on the other hand rated only 4% better in the Cinebench R10 Shading Test. 作者: boris_lee 时间: 2011-1-6 13:05
