Furthermore, a control field is provided which is arranged to provide a programmable value specifying a decimal point location within the fixed-point representation of the number, and the data processing unit is operable to reference the control field and to control the formal conversion operation ...
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 ...
The term ‘fixed point’ refers to the corresponding manner in which numbers are represented, with a fixed number of digits after, and sometimes before, the decimal point. With floating-point representation, the placement of the decimal point can ‘float’ relative to the significant digits of ...

This chapter introduces more arithmetic operators and tackles the problem of handling decimal points using only whole numbers, i.e., fixed-point arithmetic.
focus on the areas outside the traditional fixed-point DSP development model, and explore the design opportunities brought by floating point DSP.Different digital formats The basic difference between fixed point and floating point DSP is that they differ in number representation of data. Fixed ...
fixed-point approximationfixed-point systemThis 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...
The present embodiments relate to circuitry that efficiently performs floating-point arithmetic operations and fixed-point arithmetic operations. Such circuitry may be implemented in specialized processing blocks. If desired, the specialized processing blocks may include configurable interconnect circuitry to sup...
Convert a floating-point system to an equivalent fixed-point representation. The Fixed-Point Tool automates the task of specifying fixed-point data types in a system. In this example, the tool collects range data for model objects, either from design minimum and maximum values that you specify...
英文: In a floating point representation system, to make an adjustment to the fixed point part and the corresponding adjustment to the exponent in a floating point representation to ensure that the fixed point part lies within some prescribed range, the real nu 中文: 在浮点表示方法中,调整浮点...
