result to specified result words.
248
(@)53 DVB BINARY DIVIDE Divides four-digit hexadecimal dividend by four-digit hexa-
decimal divisor and outputs result to specified result words.
248
(@)54 ADDL DOUBLE BCD ADD Adds two eight-digit values (2 words each) and content of
CY, and outputs result to specified result words.
230
(@)55 SUBL DOUBLE BCD
SUBTRACT
Subtracts an eight-digit BCD value and CY from another
eight-digit BCD value and outputs result to the result
words.
233
(@)56 MULL DOUBLE BCD
MULTIPLY
Multiplies two eight-digit BCD values and outputs result to
specified result words.
236
(@)57 DIVL DOUBLE BCD
DIVIDE
Divides eight-digit BCD dividend by eight-digit BCD divisor
and outputs result to specified result words.
237
(@)58 BINL DOUBLE BCD TO
DOUBLE BINARY
Converts BCD value in two consecutive source words into
binary and outputs converted data to two consecutive re-
sult words.
205
(@)59 BCDL DOUBLE BINARY TO
DOUBLE BCD
Converts binary value in two consecutive source words
into BCD and outputs converted data to two consecutive
result words.
206
60 to 69 For expansion instructions.
(@)70 XFER BLOCK TRANSFER Moves content of several consecutive source words to
consecutive destination words.
182
(@)71 BSET BLOCK SET Copies content of one word or constant to several consec-
utive words.
181
(@)72 ROOT SQUARE ROOT Computes square root of eight-digit BCD value and out-
puts truncated four-digit integer result to specified result
word.
241
(@)73 XCHG DATA EXCHANGE Exchanges contents of two different words. 183
(@)74 SLD ONE DIGIT SHIFT
LEFT
Left shifts data between starting and ending words by one
digit (four bits).
177
(@)75 SRD ONE DIGIT SHIFT
RIGHT
Right shifts data between starting and ending words by
one digit (four bits).
177
(@)76 MLPX 4-TO-16/8-TO-256
DECODER
Converts up to four hexadecimal digits in source word into
decimal values from 0 to 15 and turns ON, in result
word(s), bit(s) whose position corresponds to converted
value.
Can also convert up to eight hexadecimal digits and turn
ON corresponding bits in result words R to R+15.
209
(@)77 DMPX 16-TO-4/256-TO-8
ENCODER
Determines position of highest ON bit in source word(s)
and writes the ON bit’s position (0 to F) to digit(s) in R.
Can also determine the position of the highest ON bit in
one or two groups of 16 words (S to S+15, S+16 to S+31)
and writes the ON bit’s position (00 to FF) to byte(s) in R.
212
(@)78 SDEC 7-SEGMENT
DECODER
Converts hexadecimal values from source word to data for
seven-segment display.
215
(@)79 FDIV FLOATING POINT
DIVIDE
Divides one floating point value (Dd+1, Dd) by another
(Dr+1, Dr) and outputs the result to R+1 and R.
238
(@)80 DIST SINGLE WORD
DISTRIBUTE
Moves one word of source data to destination word whose
address is given by destination base word plus offset.
183
(@)81 COLL DATA COLLECT Extracts data from source word and writes it to destination
word.
185
(@)82 MOVB MOVE BIT Transfers designated bit of source word or constant to des-
ignated bit of destination word.
187
(@)83 MOVD MOVE DIGIT Moves hexadecimal content of specified four-bit source
digit(s) to specified destination digit(s) for up to four digits.
188
(@)84 SFTR REVERSIBLE SHIFT
REGISTER
Shifts data in specified word or series of words to either left
or right.
173
(@)85 TCMP TABLE COMPARE Compares four-digit hexadecimal value with values in table
consisting of 16 words.
