WebNot all the 39 bits need to be part of the opcode. In general the bits of the opcode fields are calculated from the number of opcodes, which has not been given. Those 39 bits can be used or reserved for future use. For example, 3 bits could be used to specify a byte in each word (thereby extending the address bits). WebUses multiple registers to store data; leads to faster execution than accumulator and computers can generate more efficient code by using registers as temporary storage; used by most systems today.
