More on chips from space Micron and Elvis

The Russian company "Micron" (included in industry holding RTI) has developed a chip that will ensure trouble-free operation in space for 10-15 years.

On a single silicon wafer is placed more than a dozen chips, and they are all different, but equally intended as a lofty goal. They will install on computers spacecraft.

According to Nikolai Shelepina, Deputy Director General for Research of "Mikron", the new development will help companies avoid such partial failures of our spacecraft, most of which have foreign components that are not intended for use in space. 

Constructors Zelenograd enterprise "Micron" worked on the design of these chips 3 years. The problem compounded by the fact that the space, in addition to the temperature effect on computer systems have a high radiation and strong electromagnetic pulses.

Gennady Krasnikov, head of the group of companies "Micron" expects that within 1-2 years developed by experts from Zelenograd "space" chips will be used in creating massively Russian satellites and equipment to them. "And then our devices in space will be very reliable," — he stressed.

In addition to space, the new chips undoubtedly will be widely used in aviation, and in Russian military equipment. At present, "Micron" is already producing 42% of microelectronics in the country. It is produced millions of tickets for transport, chips for biometric passports, the SIM card.

The fastest and most completely domestic: ELVIS develop a new microprocessor for satellites

The latest development of the Zelenograd NPC "Elvis" — a microprocessor MC-30SF6, which extends the range of multi-core processors "Multicore" — became the subject of several publications in the media: "Russia creates a slower processor for satellites," wrote the "News". Elvis did not believe in a slow processor and emphasize that at present it is the "fast" signal microprocessor for use in space-based sensors, in harsh environments — large range of temperatures and radiation emission. Make new chips will be at Zelenograd "Micron". Key features of the new "space" chip and its competitive advantages edition Zelenograd.ru found out the developers. "Compared with domestic and foreign counterparts our processor provides exceptional performance and the availability of built-in Gigabit links SpaceFibre, — told in Elvis. — For example, only on the core DSP chip that is ten times faster than the processor installed in the American Mars rover Curiosity. A JPEG-compression of images at a rate of 320 megapixels per second run in parallel separate hardware accelerator. According to the preliminary specifications — we are developing the fastest by far the world's radiation-resistant processor, except for highly specialized FPGA, where comparable performance can be achieved by any one particular task, while the rest will be cut functionality. MC-30SF6 processor can be used in on-board electronic equipment: a path of processing of optical and radar systems, video cameras, data processing and image compression in a radio link. The area of application is not limited to the sphere of space: it can be, for example, avionics. "

The development of the new microprocessor to the end of 2014 allocated 220 million rubles — the Ministry of Industry of the funds under the federal program for the development of electronic components by 2020. Chips will be manufactured in the Zelenograd "Micron", at the end of 2014 should complete the development of an experimental batch release. Thus, the IC will fully domestic — all operations on its creation, from design to manufacture and encapsulation will be implemented in the territory of the Russian Federation.

To protect against radiation processor chip MC-30SF6 projected on the basis of radiation-resistant library, specially designed for the factory "Micron". This approach is implemented in Russia for the first time Elvis, and this is not the first development based on it: initially the same library in the enterprise created under foreign factory, on the basis of which a number of chips — before launching in Zelenograd line of chips 180 nm. An example of the already completed design — the memory chip 1657RU1U,won first prize in the contest "Golden Chip 2013"for unique to CMOS technology parameters of radiation resistance. In a similar way to design processors (RadHard by Design) perform only a few companies in the world, for example, Aeroflex and Atmel. In Russia, on the "Micron", has already been successfully fabricated and tested three-part type of radiation-resistant VLSI designed Elvis, in parallel is even more projects.

The new processor is designed for continuous operation in techenie10-15 years in a large temperature difference (minus 60 º C to 85? C) and the total cumulative dose of radiation up to 200 kilorad (all the advanced features). The topological level of the processor chip — 180 nm. Clock frequency in different nuclei — from 100 to 160 MHz, while in Elvis noted that performance can not usually measured in MHz, and the number of operations per second — and it it is more than competitive. Another of its competitive advantage — cost: through the use of relatively inexpensive technology — CMOS — chips produced at times cheaper counterparts, which are usually made on the technology "silicon on insulator" (SOI).

"There are several approaches to improve the radiation resistance of electronic components — explain to developers. — First — the use of appropriate production technologies such as SOI or SOS — "silicon on sapphire." This is an expensive option, but it allows you to achieve the best parameters chip resistance to radiation. The second approach — we have chosen — a special design methods (topological solutions, other forms of transistors, redundancy at the level of the standard cells), it provides acceptable for most applications, the parameters of durability at a fraction of the cost of manufacturing chips. The third approach — the failure-tolerant solutions at a higher system level (architecture chips, modules, devices), such as data redundancy, error control codes, special analysis algorithms and work with faults, etc. "

Elvis processor extra protection against radiation will produce a physical CPU registers triple redundancy, and protection of the internal and external memory Hamming code, automatically correcting errors. "But the above-mentioned" Izvestia "," silica coating "and" body with gold "is not really used to protect against radiation — correct errors in Elvis journalists. — And the architecture of the processor not MIPS, which "was built processor hapless vehicle" Phobos-Grunt "- the architecture in MC-30SF6 only one integrated core. Our processor is a system on a chip with two independent processors DSP and CPU (architecture MIPS), and the hardware accelerator compression JPEG, accelerator operations, and filtered spectral processing and high-speed integrated communication channels. As for MIPS — this processor architecture has nothing to do with the hapless "Phobos-Grunt", the words of the representative NIIET misinterpreted. The term "processor" is often referred to is not the CPU chip, the CPU module, a digital computer or a PC system unit. According to official findings of the Commission for the reasons of failure of equipment "Phobos-Grunt", indeed, the whole architecture of the machine considered insufficiently robust, no algorithms have been implemented in a number of emergency situations — but it does not go on the processor chip. "

At the same time Elvis and partnership with, the development of its own line of radiation-resistant chip lea
d and "Micron". Over the past three years, its designers have created a number of microprocessors and other schemes that satisfy the requirements of Russian standards, and must ensure the smooth operation of spacecraft on-protyazhenii10 15 years — this in a recentstoryTV channel "Vesti" said Nikolai Shelepin, Deputy Director General for Research and NIIME "Micron". According to him, in the fall of Russian satellites often to blame for imported chips, which do not always meet the space requirements or not intended for use in space. "We expect that in the short term, a year or two will be very widespread use of our components. And our machines in space will be very reliable, "- said Gennady KRASNIKOV, head of the group of companies" Micron ".
