WebFeb 6, 2024 · The signed shift n>>31 converts every negative number into -1 and every other into 0. When we do a -n>>31, if it is a positive number then it will return -1 as we are doing -n>>31 and the vice versa when we do for a negative number. But when we do for 0 then n>>31 and -n>>31 both returns 0, so we get a formula: 1 + (n>>31) – (-n>>31) WebDec 10, 2013 · I'm new to verilog and have a question about signed multiplication.
