C-FLEA: A complete C virtual machine development and runtime environment

    C-FLEA is a "virtual machine", which was designed from the "ground up"
    to run 'C'. Provides an easy way to implement 'C' on CPU's that are not
    supported with standard 'C' compilers, are too small/weird for efficent
    native implemention of C, or use a system design requiring memory that
    is not directly executable (eg: serial). The C-FLEA can also be used to
    implement 'C' application languages embedded within other programs, and
    has many other useful purposes.
    - Includes a complete development environment for the C-FLEA VM, which
      contains C compiler, optimizer, library, Assembler, linker, IDE, make,
      simulator with remote target debug capability and much more.
      (Similar to MICRO-C Developers Kits, and EMILY52 in this catalog).
    - Includes sample virtual machine implementations for:
        6800/01/02/03/08/11, 6805, 8051/52, 8086 and PIC processors.
    - VM rquires about 1K of code, and only a few bytes of RAM.
    - Much faster and more space efficent than language interpreters.
    - Can execute from standard (parallel), serial (I2C etc.) memory, or
      any other memory addressing scheme you may wish to use.
    - C-FLEA Instruction is very efficent for C, resulting in large/complex
      programs requiring minimal (less than expected) code space.
    - Tiny/Powerful "C-Stamp" can be built from two chips (CPU+I2C memory).
    - This package is licensed for single use. Low cost runtime licensing
      is available should you wish to re-distribute the VM interpreter.
    Complete C-FLEA package : $99.95 US     ($129.95 CDN)

Q: Is MICRO-C a full ANSI compiler?

    No, MICRO-C is a "near ANSI" subset compiler. It does however, support
    more of the 'C' language than most other subset compilers, including:
      - All 'C' statements:
        if/else     while   do/while    for     break   continue
        return      goto    switch/case/default {}      ;       asm
      - All 'C' operators:
        +  -  *  /  %  &  |  ^  <<  >>  >  <  == ~ ++ -- ?: , . ->
        += -= *= /= %= &= |= ^= <<= >>= >= <= != ! () [] sizeof
      - The following data types:
        int     char    unsigned    (including: unsigned char)
        struct  union   extern  static  register   void
        *(pointer to any type, incl. pointers and structs)
        - Arrays of any type (incl. multi-dimension, pointers & structs)
        - Function can return any type
        - Typecast of values to other types
      - Decimal, Octal and Hex constants. eg: 127, 0177, 0x7f
      - Full support for strings and character constants: ('' "")
        Including: \n \r \t \b \f \177(Octal) \x7F(Hex)
        (16 bit character constants are supported. eg: 'ab')
      - Inline assembly code (single or multi statement).
      - Preprocessor commands:
        #define     (fully parameterized & multi-line)
        #undef
        #forget     (multi undef -similar to FORTH forget)
        #error
        #include
        #if/#ifdef/#ifndef/#else/#endif (fully nested)
        #file       (sets filename displayed in error messages)
      - It DOES NOT support:
        Typedef, Long* / Double / Float / Enumerated data types, Bit fields.
      * 32 bit "long" number math functions are provided in the library.
        These may be easily adjusted to manipulate even larger numbers.
        (8051 Compiler also includes a floating point library)

Q: Does MICRO-C support the (insert favorite processor)?

    See the CATALOG for a list of processor families which we directly
    support. The compiler is configurable to support variants within a
    family (extra registers/peripherals, different memory maps etc.).

    If you need support for a different processor, please check with us.
    We may be planning a release for the processor you want.

Q: Does MICRO-C run on a (Macintosh, UNIX box, etc...)?

    At the present time, all of our products run under (MS)DOS or a DOS
    compatible operating system/emulator.

Q: I heard that you sell source code, why is it not in the catalog ?

    Due to many legal and support problems, we no longer sell the source
    code to any of our products.

Q: Does MICRO-C output assembly code?  Do I need an assembler?

    MICRO-C generates assembly code. All developers kits include our XASM
    cross assembler, which our IDE and CC commands automatically run for you,
    giving you a "one step" compile.  A command option allows you to include
    the 'C' source code as comments in the ASM listing.

Q: How much code can I fit in (nK) of memory?

    That depends on so many factors that its impossible to give you a general
    answer. It is usually more that you would think, because MICRO-C produces
    fairly compact code. This is especially true with our "Developers Kits",
    because their libraries are hand-coded in assembly language, using very
    tight code. Here are some examples of appications:

    MICRO-C Compiler (compiled itself!)                     23K
    ANSI terminal with built in XMODEM file transfer        10K
    Combination lock (rotary encoder, led indicator)        2K
    Telephone "distinctive ring" switcher (1 - 3 lines)     1K

Q: What are the "extras" included in the developers kits?

    LOTS of good stuff! Application notes. Utilities: Editors, File/Directory
    manupulation, TSR browser, listing and symbol table utilities, MAP file
    generator, ASCII encoder/archiver, Complete COMM/TTY package... more.
    Tiny MS-DOS compatible file system in C. Files for "embedding" PC's,
    Multi-tasking kernal for some cpu's. Not to mention all the good stuff
    on our DEMO diskette which is included at no charge.

Q: Is your EMILY52 simulator really that fast?

    EMILY's speed is dependant on your PC (>150,000 inst/sec on 386/25,
    >500,000 inst/sec on 486/33).

    My tests have shown EMILY on the 386/25 to be roughly equivalent to a
    4Mhz 8052. For example, a customer reported that an algorithm that
    should take about 1 second on a 12Mhz 8052 took 3 seconds under EMILY.
    The same program took over 20 MINUTES under another popular simulator.

Q: Is MICRO-C really as good as you say it is?

    Sturgeons Rule has it that 90% of science fiction is junk. A similar
    rule applies to PC software, but I'd say that 90% is a lower bound.
    Once in a while, though, you find a product that makes up for the rest..
    If price has kept you out of the microcontroller C market, you have no
    further excuses. Micro-C is as good as it gets!

    I just obtained Micro C, and I'm very impressed!...
    The portability of Micro C is second-to-none, as is it's professionally
    written code and overall usability... I need to emphasize here that
    Micro C is by far the best coded compiler I've ever seen. This excellent
    code quality extends throughout all associated modules.

    Dave, Thanks for responding to the minor problem I had with your
    wonderful little compiler.
