WebAug 31, 2024 · As I understand, when reading two bytes from an unaligned address, the read is done in two clock cycles - first, the odd-address byte, and then the even-address byte, from the modified address (i.e. the original 19 bit address plus one). My question is: why are two clock cycles required to accomplish this? WebComputers perform four tasks: input+processing+output+storage. True.
