WebAug 14, 2016 · One way of finding the index of the r-th 1-bit in mask is to tally the 1-bits using a classical population count algorithm based on binary partitioning, and record all of the intermediate group-wise bit counts. We then perform a binary search on the recorded bit-count data to identify the position of the desired bit. WebMy goal is just squaring a value so is there a way to define a “multiply” circuit acting only on the bits storing the value to be squared and then store that value in a new register. This would amount to finding some kind of mapping between the locations of the 1s in the bitstring we want to multiply to the locations of 1s in the result. afpa d\u0027arrasWebJul 15, 2024 · Count total bits in a number Difficulty Level : Basic Last Updated : 15 Jul, 2024 Read Discuss Courses Practice Video Given a positive number n, count total bit in it.
