Making floating point math highly efficient for AI hardware

WebFloating-point numbers have two advantages over integers. First, they can represent values between integers. Second, because of the scaling factor, they can represent a much greater range of values. On the other hand, floating point operations usually are slightly slower than integer operations, and you can lose precision.

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. WebSep 22, 2024 · Equivalent statement for floating point variables. f32Var1 += (f32Var2 * f32Var3); requires 10 clock cycles to execute, where f32Var1, f32Var2 and f32Var3 are local float variables. So fixed point math (using the DSP instructions) is faster than floating point math (using FPU). But the difference is marginal.

WebFloating point (32 bit) has better precision and a higher dynamic range than fixed point (16 bit) . In addition, floating point programs often have a shorter development cycle, since the programmer doesn't generally need … 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.

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. how many miles is the bay bridge
