Fix point algorithm
This example shows the development and verification of a simple fixed-point filter algorithm. We will follow the following steps: 1) Implement a second-order filter algorithm and simulate in double-precision floating-point. 2) Instrument the code to visualize the dynamic range of the output and state. 3) … See more We develop our algorithm in double-precision floating-point. We will use a second-order lowpass filter to remove the high frequencies in the input signal. See more To convert to fixed point, we need to know the range of the variables. Depending on the complexity of an algorithm, this task can be simple or … See more We convert variables to fixed-point and run the algorithm again. We will turn on logging to see the overflows and underflows introduced by the selected data types. See more Let us first analyze the information displayed for variable z (state). From the histogram we can see that the dynamic range lies between ( ]. By default, the scope uses a word … See more WebTypically, an algorithm is accompanied by code that sets up input data and code that creates plots to verify the result. Since only the algorithmic code needs to be converted to fixed point, it is more efficient to structure the code so that a test file creates inputs, invokes the core algorithm, and plots the results, and algorithmic files perform the core …
