A data processing apparatus and method are provided for converting a number between fixed-point and floating-point representations. More particularly, the data processing apparatus comprises a data processing unit operable to execute instructions, with the data processing unit being responsive to a ...
4.3.1. Floating-Point versus Fixed-Point Representations An FPGA contains a substantial amount of logic for implementing floating-point operations. However, you can increase the amount of hardware resources available by using a fixed-point representation of the data whenever possible. The hardware ...

This paper presents a new data representation known as Dual FiXed-point (DFX), which employs a single bit exponent to select two different fixed-point scalings. DFX provides a compromise between conventional fixed-point and floating-point representations. It has the implementation complexity similar ...
constructor takes as argument an integer, or a string. Floating point numbers must be converted to a string before being used to create aDecimal, letting the caller explicitly deal with the number of digits for values that cannot be expressed exactly using hardware floating point representations. ...
Conclusions Going further than previous attempts, the present results suggest that the proposed method, in addition to helping designers in determining the number of bits for fixed-point representations, can also aid in defining details about filter realization and structure....
Furthermore, you can take a look at "Intel FPGA SDK for OpenCL Best Practices Guide, Section 3.3.1 Floating-Point versus Fixed-Point Representations" and follow the guidelines to mask out bits to see if you can get the desired results. If none helped, I recommend opening a ticket with ...
This chapter introduces more arithmetic operators and tackles the problem of handling decimal points using only whole numbers, i.e., fixed-point arithmetic.
Composed of a mantissa and exponent Floating point processor can also support integer representation and calculations. There are two floating-point data representations on the C67x processor: single precision (SP) and double precision(DP). 10 Digital Signal Processing - Single precision and double ...
DATA PROCESSING APPARATUS AND METHOD FOR CONVERTING NUMBER BETWEEN FIXED-POINT AND FLOATING-POINT REPRESENTATIONS PROBLEM TO BE SOLVED: To provide a data processing apparatus and method for converting a number between fixed-point and floating-point representations. CN Hinds,クリストファー ニール ハ...
