3-Eng Java baner

We executed testing of all Java Virtual Machine  (JVM) from Sun Microsystem, developed  programming tools, launched 14 releases of conformance suite JCK in partnership with manufacturer. This experience is succesfully applied to imlementation of  system software projects.

Implementation of Russian version of Java (Moscow, since 2011)

New version of Java-type platform is realized for Russian CPU Elbrus. It is a fully secure implementation, free of malicious logic and backdoors in hardware and software. thia verson supports all built-in security features of native Java. Currently we are increasing performance of Russian JVM, porting new libraries and applications.


  • Developed on the base of OpenJDK JVM
  • JIT (just-in-time) compiler is implemented optimized for Elbrus platform
  • Special  libraries are ported for Elbrus architecture (OpenGL, OpenCV etc.), some widely spread opensource applications and libraries (Apache Tomcat, Apache Derby, Eclipse, Apache Jmetter etc.)

J2SE class libraries (OpenJDK), Java virtual machines, Just-In-Time compilers, C, C++, ????

Implementation of Russian version of JavaScript (Moscow, since 2016)

Porting is going for virtual machine JavaScript V8 of oen-source Chrome browser to "Elbrus" platform .

  • Porting and adaptation of legacy compilers and interpreters
  • Validation of correct processing all of functions
  • Performance improvement

Technologies: from Chromium project

Porting of С# virtual machine to "Elbrus" platform (Moscow, since 2016)

Implementation of C#  language support for "Elbrus" hardware platform.  Mono project is taken as a basis  implementing the set of tools compatible .NET Framework compatible with .NET Framework (compiler from C# language,  virtual machine Common Language Runtime, and others.

Технологии: Common Language Runtime (CLR), .NET Framework, Just-In-Time compilers, Ahead-Of-Time compilation, LLVM, C#, C, C++, Assembler

Custom implementation of J2SE platform (Ireland, 2011-2015)

Customer is advancing a novel server virtualization technology specifically tailored to x86 enterprise application environments. The technology features high reliability and performance with superior cost-efficiency and manageability. The first software platform planned for this technology is the Java Platform. Any Java application will operate on new technology-based array automatically and transparently.
J2SE class libraries (Apache Harmony, OpenJDK), Java virtual machines, Just-In-Time compilers, C, C++, Mercurial

  • technology utilizes arbitrary inexpensive, off-the-shelf servers, assuring the lowest possible cost of entry
  • hot-swappable, can work in fully redundant mode to tolerate failures
  • technology is embedded under the covers, no apps re-engineering is required
  • the Java platform implementation allows to switch between available class libraries on startup
Implementation of testing frameworks for J2SE API libraries (Sun Microsystems, 199х -20хх)

Extensive work with a wide range of Java API libraries led to the strongest experience in this area of ~ 60 man-years. Libraries covered:

  • Core Java packages (java.lang and subpackages)
  • Basic mathematics API
  • Java Management Extension API (
  • Sound API (javax.sound)
  • Printing API (javax.print)
  • XML processing (DOM, SAX) API
  • Image I/O API (javax.imageio)
  • Java utility API (java.util)
  • Networking API (
  • Java I/O API (, java.nio)
  • Implementation of CJK and other character encodings
  • Java security API (JAAS, JCE, JSSE)
Fortran 77/90/95/F2K compilers (for several vendors, 199х-20хх))

  • front-ends and back-ends development
  • development of new and missing features
  • optimizations of various performance issues
