"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. " - Bit shifting in verilog

WebMay 23, 2014 · Third is that a 4 bit number times a 4 bit number will result in an 8bit answer, not 16bit. In any case, unless you are working at very high speeds you should be able to perform a multiply in a single cycle. Here are a couple of ways of writing this code more naturally: Combinatorial Style WebBasically your code ignores the input A because you are assigning it to a non-existent variable. Secondly, your second code uses a bit shift ( >> ), not an arithmetic shift ( >>>) so will not perform sign extension (see below). The result your second module calculates is exactly the correct result for the hardware you have described.

WebSep 29, 2024 · What you want to do is to shift right by 5 bits (8-3=5): (8 - bits_to_rotate). This will shift all 8 bits to the right by 5 positions, dropping the 5 LSB's and adding 5 0 bits to the MSB's. This gives you 8'b0000_0011. Then, when you do the bitwise OR of the 2 terms, you get: 8'b0001_0000 8'b0000_0011 = 8'b0001_0011. Change: WebNov 12, 2013 · This is known as a logical shift, since it strictly follows the logical definition of "shifting", that is, moving the existing bits one position towards the LSb. If we shift in the same value as the MSb, we change the value but retain the sign: 0b0110 (6) -> 0b0011 (3) 0b1110 (-2) -> 0b1111 (-1)
