   • 2^n` is the order of `3^n

     Top Answer

     Answered Aug 05, 2016 · 6 votes

     Big-O is an upper bound. It basically says 2^n does not grow faster than 3^n, which is true.

     Arguably, the meaning of the colloquial 'is in the order of' is closer to another Landau symbol, the Big-θ, which is both an upper and lower bound.

     2^n is not an element of θ(3^n), as 3^n grows significantly faster.

   • 2^n to n priority encoder w/ continuous assignments

     Top Answer

     Answered Oct 18, 2020 · 2 votes

     You cannot do it in an algorithmic way using generate blocks. Generate blocks are evaluated at a pre-processing step before real program compilation and therefore cannot be conditioned based on dynamical variables.

     You can write an expression like the following:

     assign encoder_out = (encoder_in >> 1) == 1 ? 1 : (encoder_in >> 2) == 1 ? 2 (encoder_in >> 3) == 1 ? 3 : 0; -

     If you can see it is recursive and you need to flatten out the recursion levels manually and cannot use a recursion of loops to do it in generate blocks. You would need a dynamic function with a dynamic loop.

     Here is a suggestion. You can call a function from the assign statement. Not sure if this is synthesizable, but it explains a possible alternative to the always blocks.

     function logic [SIZE_OUT:0] encode(input logic [SIZE_IN :0] encoder_in); for (int i = SIZE_IN-1; i >= 0; i--) begin if (encoder_in[i]) begin return i; end end return 0; endfunction assign encoder_out = encode(encoder_in);

     You have a little error in your algorithm. The idea is that for each pixel of pix, share1 and share2, we have the following relation :

     share2 = pix XOR share1-

     This translates into :

     if pix[j, i] == share1[j, i]: share2[j, i] = 0else: share2[j, i] = 255

   • 2^n mod (m) algorithm

     Top Answer

     Answered Oct 13, 2011 · 0 votes

     The n part is clear, as you have already understood yourself. The size(m) (which is the number of digits in m, which is basically log(m)) is because of mod. Even though your CPU does that for you in one instruction, it takes log(m) (let's say 32 bits) times. If m is very large, as is common with encryption keys, this can become considerable.

     Why number of digits in m? Remember division:

     abcdefghijk | xyz |-----alm | nrvd... opq stu wabc .......

     The number of times you do the minus, is at most the number of digits in the dividend.

     Generate all subsets of a set with n elements.

     Added. The simplest way of generating all the subsets of S = {a0, a1, ..., an-1} is probably to translate between the binary representation of the rank and the subset.

     Take S = {a0, a1, a2}.

     rank binary subset0 000 {} 1 001 {a0}2 010 {a1}3 011 {a0, a1}4 100 {a2}5 101 {a0, a2}6 110 {a1, a2}7 111 {a0, a1, a2}

     So, a 1 in the binary means the corresponding element is in the subset. A 0 means the element is not in the subset.

     But you should also lookup Gray code.

   How do I calculate the number of subnets in a network?

   • To calculate the number of subnets in a network, use the formula 2^n, where n is the number of bits used for the subnet mask. For example, a subnet mask of 255.255.255.192 (or /26 in CIDR notation) uses 6 bits for the subnet mask, so the number of subnets is 2^6, or 64.

   What is subnetting & how does it work?

   • Subnetting is the technique of dividing one big network into multiple small networks. Subnet makes the network more efficient and easy to maintain. Subnets provide a shorter path to network traffic without passing through unnecessary routers to reach their destinations.Subnetting makes network routing much more efficient.

   Every IP network needs two specific addresses network address and broadcast address.

   All addresses between the network and broadcast addresses are known as valid host addresses. Any device that uses the IP protocol to transfer data needs a valid host address.

   How does it work? Here is kind of a loose analogy that should make this very clear. Think of an IP address as your postal address. Let's take 191.54.38.15 for example. In our analogy, each set of numbers may represent a geographic area. As we move from the left to the right, the geographic area continuously becomes more and more specific.
