_Deposit Index Adder_ (10 usec.)
dia x Y Operation Code 16
The C(IA) replace the octal digits 7 through 11 of memory location Y.
Octal digit 6 of Y is cleared. Digits 0 through 5 of Y are left
unchanged. The x portion of the instruction is ignored.
Non-Memory Instructions
Rotate and Shift Group
This group of instructions will rotate or shift the Accumulator and/or
the In-Out Register. When the two registers operate combined, the In-Out
Register is considered to be a 36 bit magnitude extension of the right
end of the Accumulator.
Rotate is a non-arithmetic cyclic shift. That is, the two ends of the
register are logically tied together and information is rotated as
though the register were a ring.
Shift is an arithmetic operation and is in effect multiplication of the
number in the register by 2^{+N}, where N is the number of shifts. Shift
or rotate instructions involving more than 33 steps can be used for
simulating time delays. 36 rotate steps of the Accumulator will return
all information to its original position.
_Rotate Accumulator Right_ (13 usec. maximum for 36 shifts)
rar N Operation Code 671
This instruction will rotate the bits of the Accumulator right N
positions, where N is octal digits 7-11 of the instructions word.
_Rotate Accumulator Left_ (13 usec. maximum for 36 shifts)
ral N Operation Code 661
This instruction will rotate the bits of the Accumulator left N
Positions, where N is octal digits 7-11 of the instruction word.
_Shift Accumulator Right_ (13 usec. maximum for 36 shifts)
sar N Operation Code 675
This instruction will shift the contents of the Accumulator right N
positions, where N is octal digits 7-11 of the instruction word.
_Shift Accumulator Left_ (13 usec. maximum for 36 shifts)
sal N Operation Code 665
This instruction will shift the contents of the Accumulator left N
positions, where N is octal digits 7-11 of the instruction word.
_Rotate In-Out Register Right_ (13 usec. maximum for 36 shifts)
rir N Operation Code 672
This instruction will rotate the bits of the In-Out Register right N
