Intel takes the risk of entering vision
Intel Company investigate visual with eyes to replace stretches of cracked electricity overcome, appear bandwidth periodical to have more and more key microprocessor of waiter dim, in an era of tera scale calculated.
Ian Yang, advanced circuit of Intel and a Intel of the comprehensive project of technology are learnt to special member and director, international solid-state circuit meeting (ISSCC) in IEEE Propose an article and 11 combination waveguides that described of February, detection and person who modulate suitable for, combine whom photonic need develop into CMOS join each other directly at block.
Young people describe that has already demonstrated transport of 10 Gbit/s and a piece of 8 straits that receive the pace at most, performance of 90 nanometers of apparatus. Long-term goal of company to make, can reach in 100 GBps high component with wide vision between 1 TBps, Yang says.
Send information contrary to electron high-speed and low consumption and speech offer the inherent advantage through photon. But the synthesis of the monoblock of photonic required in CMOS one and component of the light produced by electricity propose a lot of challenges.
In his course of giving to ISSCC on Monday, mark is rich, course building and comprehensive Intel senior colleague and director, describe as joining each other one of the 5 greater challenges which face IC that climb 32 nanometers of nodes and in the distant place. Say the visual solution richly ” If technology can be developed, that expenses make the photon learn to bind with silicon logic effectively. ”
Study time such as West panel of expert admit computer industry want vision in its future multicore processor recently in photon those, but optics not having clear light source to agree to to drive on slice, say technology needs to reach the quite low one hotly, ability and expenses are feasible.
The light has already been used for conveying data decades. In telecommunications, in the system that the fiber attracted attention since the seventies of the 20th century is used. Photonic technology being used in the computer network and substituted the simple electron sending and short range communication more and more too.
A lot of processors systems
Intel prototype chip, a microprocessor, the photon learns to place and die on CMOS, the performance of every transistor not damaging the apparatus, Yang says. ” Because we in on die,have by those intermittently slice have the light and easy,” Yang says.
Expect, make, require to transition a lot of key microprocessor building slices of cracked I/O bandwidth that increase and in many system of processor in processor / memory interface, according to the son’s article. The building in the future will need 200 GBps to 1 TBps, the bandwidth of the article country. Electricity demand, increase complicate and expensive material in order to repay this requirement in circuit already, according to those articles.
” There is its terahertz bandwidth, low loss and low bunches of one that disturbeds have joined each other and has already been suggested the electricity replaced among stretch joins each other visually, ” Article country.
According to article, wavelength divide many way reply, spend, improve in the course of studying using for other bandwidth.
Those Intel papers describe the long-term goal create the microprocessor with combining on the concave model’s mould, silicon nitrogen thing visual waveguides the single mould, nitrogen thing waveguide silicon connects the metal germanium detection of the metal semiconductor and ring resonator modulating device based on polymer of light produced by electricity. Company hope, it reaches to be can for reach high bandwidth with energy visual component of efficiency CMOS dealt with to accord with and can it sets up to be here flow, in the same course very While sacrificing the transistor radio performance, input and export joining according to a optics of the paper.
Finally, Yang that say, Intel see photon learn technology used at chip to go, core to core and leave the chip, the core joins each other to memory.
” Join and make it possible to regulate CMOS transistor which will continue I/O bandwidth visually each other, ” Yang says.
Optical CPU joins and suitable for those parcels and imports the output for bag optics first each other, there is one at first ” The breeding ” According to the paper of Yong, single bag technology. ” If the challenge of the mere component of complete combination in CMOS course may be overcome, integrate optical spare part close to data transmission speed, TB/s I/O of route, led to to offer monolithically of 1 pJ/b right together with energy efficiency of the requirement And then,” The article is over.
