  2. IEC 60034 - Wikipedia

    en.wikipedia.org/wiki/IEC_60034

    It classifies five classes: IE1 (standard), IE2 (high) and IE3 (premium), IE4 (super premium efficiency), IE5 (ultra premium efficiency). For each class the efficiency is defined for a rated output range from 0.75 to 375 kW. In the European Community the IE2 class is mandatory for all new motors since 16 June 2011. The IE3 class will be ...

  3. Premium efficiency - Wikipedia

    en.wikipedia.org/wiki/Premium_efficiency

    Premium efficiency, when used in reference to specific types of Electric Motors (with a rotating shaft), is a class of motor efficiency.. As part of a concerted effort worldwide to reduce energy consumption, CO 2 emissions and the impact of industrial operations on the environment, various regulatory authorities in many countries have introduced, or are planning, legislation to encourage the ...

  4. Virtual method table - Wikipedia

    en.wikipedia.org/wiki/Virtual_method_table

    As such, the compiler must also generate "hidden" code in the constructors of each class to initialize a new object's virtual table pointer to the address of its class's virtual method table. Many compilers place the virtual table pointer as the last member of the object; other compilers place it as the first; portable source code works either ...

    This is particularly true for the aerospace and automotive sectors where size, weight and efficiency are driving the design of machines. [6] [7] [8] The design approach often taken is to consider both electromagnetic and thermal aspects of a machines design at the early stages in machine design, [9] [10] where Motor-CAD allows this to be done.

  6. Comeau C/C++ - Wikipedia

    en.wikipedia.org/wiki/Comeau_C/C++

    Comeau C/C++ is a compiler for C and C++ produced by Comeau Computing. Comeau C/C++ was once described as the most standards-conformant C++ compiler. [1] In 2006-2008 it was described as the only mainstream C++ compiler to fully support the export keyword for exported templates. [2] [3]

  7. C99 - Wikipedia

    en.wikipedia.org/wiki/C99

    Cover of the C99 standards document. C99 (previously C9X, formally ISO/IEC 9899:1999) is a past version of the C programming language open standard. [1] It extends the previous version with new features for the language and the standard library, and helps implementations make better use of available computer hardware, such as IEEE 754-1985 floating-point arithmetic, and compiler technology. [2]

  8. Instructions per second - Wikipedia

    en.wikipedia.org/wiki/Instructions_per_second

    The first PC compiler was for BASIC (1982) when a 4.8 MHz 8088/87 CPU obtained 0.01 MWIPS. Results on a 2.4 GHz Intel Core 2 Duo (1 CPU 2007) vary from 9.7 MWIPS using BASIC Interpreter, 59 MWIPS via BASIC Compiler, 347 MWIPS using 1987 Fortran, 1,534 MWIPS through HTML/Java to 2,403 MWIPS using a modern C / C++ compiler.

  9. Parallax Propeller - Wikipedia

    en.wikipedia.org/wiki/Parallax_Propeller

    Parallax supports Propeller-GCC which is a port of the GNU Compiler Collection (GCC) compiler for the programming languages C and C++, for Propeller [13] (branch release_1_0). The C compiler and the C Library are ANSI C compliant. The C++ compiler is ANSI-C99 compliant. Full C++ is supported with external memory.
