The division in Long Xin discloses before this, long Xin 3A6000 already flowed piece come back, but pass initial test only, sequel still has function to try to find out the real intention, optimize the course that changes with the product, and the time that the product that finish spends a plan to need half an year to arrive one year. Go up oneself the month begins, dragon core engineer has undertaken for Linux comfortable match, the stability on the 3A6000 series processor that so that be in,its are about to roll out runs Linux.

Long Xin released new Linux patch on June 14, show processor of Long Xin 3A6000 will support at the same time multi-line Cheng (SMT) technology. Be similar to be similar to Intel, AMD and POWER processor commonly, SMT can make logistic core amount turns over times, namely 4 nucleuses 8 lines Cheng this kind of form.

Note: At the same time multi-line Cheng (Simultaneous Multithreading, SMT) also call synchronous multi-line Cheng, intel sale technical terms namely " Cheng transcending a line " , it is a kind of technology that improves those who have hardware multi-line Cheng to exceed efficiency of whole of scalar quantity CPU. At the same time multi-line Cheng allows the executive line Cheng of many independence to use the resource that contemporary processor framework provides better.

From the point of current and foregone information, long Xin 3A6000 advocate frequency is 2.5GHz, use design of passageway of memory of 4 nucleuses, double DDR4-3200, the single-track Cheng of SPEC CPU2006 nods Base to assign a value more than 40 minutes surely, floating-point assigns a value more than 50 minutes, multi-line Cheng is worth more than 140 minutes bit minutes surely, floating-point assigns a value more than 130 minutes.

The division in Long Xin thinks the function of 3A6000 can is opposite the Zen 2 of the AMD of mark 7nm, be equivalent to Intel the 10th acting cruel farsighted level.

In addition, the government discovers in the test, long Xin GCC is compiled implement compile with the GCC of X86 implement have certain difference, the dynamic instruction of many application counts more apparent than X86 on the high side, after estimation undertakes compiling optimizing, still can rise further run minute of circumstance.

Longxin emphasizes: Long Xin can rise continuously advocate frequency, but won't go current the is frequency sacrifice efficiency technology course of Intel, strive for reduce cost and power comsumption continuously on 3GHz level.

Be worth what carry is, next generation of Long Xin 3A6000 will be 3B6000, use 4 big 4 small 8 nucleuses design, buy grinds oneself inside GPU. Big nucleus is striven for optimize through the structure improve performance again 20% above, but the government thinks it is difficult to hold out oneself.

Long Xin is even on the foundation of 3B6000, use more advanced technology to develop 3A7000 or 3B7000. The technology that second half of the year will develop more advanced technology intends the work (because Longxin insists to grind oneself IP, need the PHY such as custom-built memory interface, PCIE interface, need time 1 year roughly) .
