Instead of calculating the last 10 input values’ average, which is a FIR, you could calculate a moving average by adjusting an already calculated average based on the next input value. Moving average is a filter that averages N points of previous inputs and makes an output with them. Depending on the kernel size it might worth using a binary-insertion-sort algorithm instead, but I would like to avoid to use any recursive algorithm. Web. This VHDL implementation of moving average algorithm configures the moving average length as a power of two. Abstract: Digital filters play a major role in Very Large-Scale Integration Technology (VLSI), as most VLSI systems use addition as an integral operation.
