WebJul 12, 2024 · When designing digital circuits, we frequently make use of shift operations. As a result, verilog provides us with a simple technique for implementing these functions. The shift operator actually requires two arguments. The first of these is the name of the signal which we want to shift. The second argument is the number of bits we want to shift. WebMay 5, 2010 · As you can see, multiplication can be decomposed into adding and shifting and back again. This is also why multiplication takes longer than bit shifts or adding - it's O (n^2) rather than O (n) in the number of bits.

WebFeb 28, 2024 · Add a comment. 1. In general, the way that is implemented is with a series of muxes. One of them selects between the input data and the input data shifted by 1 bit, the next one shifts by 2 bits, the next one by 4, etc. The bits of n are then used as the select inputs for those muxes. Shifting by 64 bits requires 6 levels of 64 bit 2:1 muxes.
