(4) Intermediate jump instruction format (Format IV)
This format consists of one 6-bit field to hold an operation code and one 26-bit field to hold a displacement (with
its LSB masked to 0). 32-bit instructions use this format.
(5) 3-operand instruction format (Format V)
This format consists of one 6-bit field to hold an operation code, two fields to specify general-purpose registers
as operands, and one 16-bit field to hold an immediate data. 32-bit instructions use this format.
(6) Load/store instruction format (Format VI)
This format consists of one 6-bit field to hold an operation code, two fields to specify a general-purpose register,
and one 16-bit field to hold a displacement. 32-bit instructions use this format.
(7) Extension instruction format (Format VII)
This format consists of one 6-bit field to hold an operation code, two 5-bit fields to specify general-purpose
registers as operands, and one 6-bit field to hold an sub-operation code. 32-bit instructions use this format.
