Just out of curiosity, why do you think floating point arithmetic is |
33 |
necessary for a flight control application? People have been doing |
34 |
fixed-point flight control and other real-time applications for at least |
35 |
fifty years, and the hardware requirements for fixed-point arithmetic |
36 |
are *always* going to be less than for floating point arithmetic. |
37 |
|
38 |
Now floating point hardware may be inexpensive enough now that it's |
39 |
*feasible* to use it for this application, but I really don't think it's |
40 |
*necessary*. |
