Boolean Operand Description
CMPR D1, D2, Transfer "D2" to "D3". Any parts of the data between "D1"
D3 and "D2" that are 0 are compressed, and shifted in order
toward "D2".
CMPW S, D1, D2 Transfer "S" to "D1". Any parts of the data between "D1"
and "D2" that are 0 are compressed, and shifted in order
toward "D2".
SHR D, n Shifts the "n" bits of "D" to the right.
SHL D, n Shifts the "n" bits of "D" to the left.
DSHR D, n Shifts the "n" bits of the 32-bit data area specified by
(D+1, D) to the right.
DSHL D, n Shifts the "n" bits of the 32-bit data area specified by
(D+1, D) to the left.
BSR D Shifts the one digit of data of "D" to the right.
BSL D Shifts the one digit of data of "D" to the left.
BITR D1, D2, n Shifts the "n" bits of data range by "D1" and "D2" to the
right.
BITL D1, D2, n Shifts the "n" bits of data range by "D1" and "D2" to the
left.
WSHR D1, D2 Shifts the one word of the areas by "D1" and "D2" to
the right.
WSHL D1, D2 Shifts the one word of the areas by "D1" and "D2" to
the left.
WBSR D1, D2 Shifts the one digit of the areas by "D1" and "D2" to the
right.
WBSL D1, D2 Shifts the one digit of the areas by "D1" and "D2" to the
left.
FIFT n, D The "n" words beginning from "D" are defined in the
buffer.
FIFR S, D The oldest data beginning from "S" that was written to the
buffer is read and stored in "D".
FIFW S, D The data of "S" is written to the buffer starting from "D". 5
