A m/c is being designed whose instructions range from 1 to 6 bytes in width, with 2-bytes instruction being most common and 5- or 6-byte instruction rarely used. Compare the following opcode encoding schemes-
i. The leftmost 3 bits in the first byte of every instruction contains a binary number (1 to 6) that indicates the width of the instruction in bytes.
ii. One-byte instructions begin with 0 in the leftmost bit position of the first byte, 2-byte instructions begins with 10, and all other instructions begin with 11 followed by a 2- bit field that indicates the number of additional bytes (beyond the third) in the instruction.
