Because fixed-point DSPs are consumed in large volumes, their price per chip is a fraction of the price of a floating-point DSP. As a result, the only developers who can reasonably justify using a ...

[Editor's note: For an intro to floating-point math, see Tutorial: Floating-point arithmetic on FPGAs. For a comparison of fixed- and floating-point hardware, see Fixed vs. floating point: a ...

The Toolbox implements fixed-point arithmetic and common processor-specific operations, such as multiply with shift and saturate. The arithmetic support matches popular DSPs like those available ...

Unfortunately, AVRs don’t have floating point arithmetic so [Alan] used fixed point arithmetic – a system similar to balancing your checkbook in cents rather than dollars.

"Dr. Gustafson has recently finished writing a book, The End of Error: Unum Computing, that presents a new approach to computer arithmetic: the unum. The universal number, or unum format, encompasses ...

In C, you have to manually consider all side effects deriving from fixed-point arithmetic, while in Ada, the compiler takes care of selecting the right operations for you.

Based on this analysis, we initially set the word length to 16 bits and the scaling factor to 2 -14 for all arithmetic blocks in the transmitter. We do this by explicitly setting the fixed-point ...

In this article, we'lI present an efficient methodology that enables the implementation of algorithms involving matrix-inversion operations in hardware with fixed-point arithmetic.

FPU challenges Floating-point representations of real numbers have significant advantages over fixed-point. For example, given a fixed bit width for binary encoding, floating-point formats cover a ...
