High points at embedded conference: Fixed, and other
Floating-point processors have altered the embedded development world, but
not always for the best. These digital signal processing powerhouses consume
power and increase cost. This has led some to look for ways to migrate designs
with less robust but still quite able fixed point alternatives.
Enter The MathWorks, Natick, Mass. At the recent Embedded Systems Conference,
the company demonstrated working automotive applications where its Simulink,
Stateflow and Real-Time Workshop Embedded Coder software was used to design and
generate code for fixed-point controllers.
The software lets developers simulate behavior and assess trade-offs between
floating-point and fixed-point designs, according to Paul Barnard, Control
Systems marketing director, MathWorks. The software can automatically generate
efficient implementations for either floating- or fixed-point controllers, and
can optimize designs to reduce RAM, ROM and execution time in the generated
