Arithmetic shift right by a 4-bit positive immediate integer
Arithmetic shift right of destination by value specified in 4
LSBs of the first operand
Arithmetic shift right of the first operand by value specified
in 4 LSBs of the second operand; places result in FFF
1-bit logical shift left of word
1-bit logical shift right of word
Logical shift right of the first operand by 16 bits, placing
result in the destination operand (new bits zeroed)
Logical word shifting with accumulation
Logical shift right by a 5-bit positive immediate integer
Bi-directional logical shift of destination by value in the first
operand: positive –> right shift
Logical shift right by a 4-bit positive immediate integer
(sign extends into FF2)
Logical shift right of destination by value specified in 4 LSBs
of the first operand (sign extends into FF2)
Logical shift right of the first operand by value specified in 4
LSBs of the second operand; places result in FFF (sign
extends into FF2)
Rotate 32-bit register left by 1 bit through the carry bit
Rotate 16-bit register left by 1 bit through the carry bit
Rotate 32-bit register right by 1 bit through the carry bit
