    Re: Some comments (long) (was: Something else is needed, I think...) —Kekoa Proudfoot
   Some comments on what Chris Phillips wrote: - as far as I know, you will not be able to implement floating point in byte code, it will be too inefficient (mostly in terms of space) - agreed, current firmware does not support fixed point well, and it (...)

    Kekoa Proudfoot wrote in message ... (...) Do you think it would be possible with improved firmware to support inline H8 code embedded in a user program? For example, a special byte code could indicate that the following code should be executed (...) (26 years ago, 6-May-99, to lugnet.robotics)

     (...) Good idea! I like it! The only problem I can see with this is I'm not sure if the H8 supports position independant code or not. If it does, then there's no problem. (...) (26 years ago, 6-May-99, to lugnet.robotics)

   (...) You might be able to do this if you were clever about it; you might be able to define an opcode that defines a native subroutine that you can call with another opcode, say, that passes in 16- or 32-bit values in registers and expects you store (...)

   (...) I should clarify this. The 16-bit software multiply takes two 16-bit numbers and stores their product in a 16-bit number. The 32-bit software multiply takes two 32-bit numbers and stores their product in a 32-bit number. The operations are (...) (26 years ago, 7-May-99, to lugnet.robotics)
