Witryna7 sty 2024 · Let n be a positive integer. Let k be its number of bits.. Then n and k are linked by this mathematical relation:. 2^(k-1) ≤ n < 2^k Where ^ represents exponentiation.. Now, logarithm is a strictly increasing function, so this relation is equivalent to: log2(2^(k-1)) ≤ log2(n) < log2(2^k)

WitrynaOn the log2 scale this translates to one unit (+1 or -1). That's a simple value, easy to recall, and it is more "fine grained" than using higher bases (like log10). A doubling on the log10... Witrynahe complains and stop. Funny enough, there's an elegant solution to it. by describing the log2 function recursive (no syntax): log2 (N) : if N=1 then return 0 else return 1+log2 (N/2) The reason is that this is for synthesis unrolled at. analysis time. So the function is expanded with concrete. numbers for N.
