Port input:
Sign-extends the 16-bit displacement to 32 bits, and
adds the extended displacement and the content of
the reg1-specified register to generate a 32-bit unsigned
port address, then reads the word data located at the
generated address while masking the address’s bits
0 and 1 to 0, and stores the word into the reg2-
specified register.

Jump and link:
Increments the current PC by 4, then saves it into r31,
and sign-extends the 26-bit displacement to 32 bits
while masking the displacement’s bit 0 to 0, adds the
extended displacement and the PC value, loads the
PC with the addition result, so that the instruction
stored at the PC-pointing address is executed next.

Register-indirect unconditional branch:
Loads the PC with the jump address value in the reg1-
specified register while masking the value’s bit 0 to 0,
so that the instruction stored at the address pointed
by the reg1-specified register is executed next.

Unconditional branch:
Sign-extends the 26-bit displacement to 32 bits while
masking bit 0 to 0, adds the result with the current PC
value, and loads the PC with the addition result so that
the instruction stored at the PC-pointing address is
executed next.

Byte load:
Sign-extends the 16-bit displacement to 32 bits, and
adds the result with the content of the reg1-specified
register to generate the 32-bit unsigned address, then
reads the byte data located at the generated address,
sign-extends the byte data to 32 bits, and stores the
result into the reg2-specified register.

Halfword load:
Sign-extends the 16-bit displacement to 32 bits, and
adds the result with the content of the reg1-specified
register to generate a 32-bit unsigned address while
masking its bit 0 to 0, then reads the halfword data
located at the generated address, sign-extends the
halfword data to 32 bits, and stores the result into the
reg2-specified register.

Word load:
Sign-extends the 16-bit displacement to 32 bits and
adds the result with the content of the reg1-specified
register to generate a 32-bit unsigned address while
masking bits 0 and 1 to 0, then reads the word data
located at the generated address and stores the data
into the reg2-specified register.
