Floating point vs fixed point

WebFor example, a fixed-point representation with a uniform decimal point placement convention can represent the numbers 123.45, 1234.56, 12345.67, etc, whereas a … WebAug 13, 2024 · A fixed-point number is represented with a fixed number of digits before and after the radix point. In FPGA, a fixed-point number is stored as an integer that is scaled by a specific implicit factor. For example, the common notation fix16_10 used by Xilinx stands for a 16-bit integer scaled by 2 10.

Relative merits of fixed point vs floating point computation?

NorthGuy said: The numbers you use in FIR filters have well-defined fixed range (e.g. 0 to 1023 coming from 10-bit from ADC). Floating point calculations only introduce a burden by keeping track of the scale when the scale is always the same anyway. Thus, fixed scale FIR is considerably faster. WebJan 30, 2024 · Here are some pretty nasty “ifs” necessary for floating-point to overtake fixed-point: if it is a 56-bit floating-point processor (i.e., 48-bit mantissa plus 8-bit exponent) or 32-bit with double-precision (requiring a large accumulator), if the parts run at the same speed as the equivalent fixed-point part, if they use the same power, and ... bpdcn treatment guidelines

Difference Between Fixed Point and Floating Point

WebFloating-Point and Fixed-Point Data Types The inputs and outputs of the communications blocks support various data types. For some blocks, changing to single outputs can lead to different results when compared with double outputs for the same set of parameters. WebWhile floating-point processors can greatly simplify the real-time implementation of a system, and effectively approximate real-world numbers, fixed-point processors carry numerous other benefits. Fixed-point processors are generally smaller, consuming less power. They also require less memory and less processor time to perform.
