New evaluation version of C6808 (version 3.0)

We've updated our popular evaluation version of C6808. It features the same optimization and code generation as the full version, subject only to the same minor limits as before: maximum 4K program bytes (HC(S)08) and 512 program bytes (RS08).

C6808 - Emulator Support

| |

C6808 can work with both the HIWAVE (CodeWarrior) emulator and P&E's emulator software.

C6808 installs a tutorial help (.CHM) file that describes how to:

  • Configure HIWAVE as a BCLIDE tool.
  • Call P&E's PROG and ICD from BCLIDE.
  • Call C6808 from P&E's WinIDE

RS08 has no Negative bit in its condition codes. Can you do signed math operations?

Yes.

RS08 has no stack: how can you perform nested function calls?

Submitted by Kirk Zurell on Tue, 2007-11-20 22:01. |

C6808 creates a stack through program code: it preserves the Shadow PC (SPC) in a local variable and restores it prior to returning.
As an optimization, it eliminates this code whenever possible. When a function calls no subordinate functions, or when the call to a subordinate function happens at specific points in program flow, the compiler eliminates the saved PC and the memory location it would require.

This approach uses no extra memory compared to a hardware stack.

Do I really need C to program RS08?

Submitted by Kirk Zurell on Tue, 2007-11-20 22:00. |

There's no reason not to use C to program even the smallest computers. C compilers improve on assemblers by:

  • Allowing the developer to work in the problem space (choosing the symbolic operations), not the solution space (choosing the machine instructions).
  • Calculating opportunities for optimization with both the algorithm and target hardware in mind.

I have an application developed with an old version. Will it compile properly with the latest version?

Submitted by Kirk Zurell on Tue, 2007-11-20 21:01. | | | | | | | | | |

Yes. If you have written your program according to our recommended practices in the product documentation, upgrading should be seamless. All Byte Craft Limited Code Development Systems have backward compatibility with previous language constructs.

Please note:

  • Improvements in the compiler can alter the generated code; this may impact your testing.
  • Device header files may change between versions. If you've written customized device header files, they may require some revision. Simply examine the stock headers that we ship with the product.

When is a branch not a branch?

Submitted by Kirk Zurell on Tue, 2007-09-25 19:45. | |

I recently got an interesting code sequence out of the compiler.
