alu part 1 class ese 345 computer architecture goal: to make an alu in vhdl how it works: we have 3 input of 128 bits and 1 output of 128 bits we will also have a signal called select that will be responsible for which alu operation we are to perform dependning on the opcode if the 24th bit of select is 0 then we will perform load immediate we will load whatever is in the select signal in the bits selected in the X 7th bit position of the output
