If a greater than comparison is made (the 16-bit variable is greater than the comparison value), then the result will not be less than zero. Actually, the same code (just with a different bit skip) can be used to test. For greater than:

To check for greater or equal to, the last three lines of the code checking for greater than are simply erased. To check for less or equal to, the three lines from not equal to are added before the check for less than. Here is the complete code for compare and skip on Reg1 less than or equal to Reg2:
movf Reg2 + 1, w subwf Reg1 + 1, w movwf _2 movf Reg2, w subwf Reg1, w btfss STATUS, C decf _2 iorwf _2, w btfsc STATUS, Z goto EqualLess_Skip btfsc _2, 7 goto EqualLess_Skip ; Get the High Byte of the Result ; Store in a Temporary Register ; Get the Low Byte ; Decrement High if Necessary ; ; ; ; ; Check for Equal to Zero If Not Zero, Jump Over Equals, Jump to the Code If Number is Negative, execute Else, Jump Over
MULTIPLICATION
For both multiplication and division, repeated addition could be used, but I nd that using a scaling routine works much better and is faster. These algorithms test bits and only operate if it is appropriate to do so. Here is multiplication that requires a separate byte for counting the iterations through Loop:
clrf Product clrf Product + 1
APPENDIX G
movlw 16 movwf BitCount Loop: rrf rrf
; Operating on 16 Bits
; Loop Here for Each Bit Multiplier + 1, f ; Shift the Multiplier down Multiplier, f ; by one
btfss STATUS, C goto Skip
; If the bit is set, add ; the Multiplicand to the ; Product movf Multiplicand + 1, w addwf Product + 1, f movf Multiplicand, w addwf Product, f btfsc STATUS, C incf Product + 1, f
Skip: ; Shift up Multiplicand and bcf STATUS, C ; Loop Around rlf Multiplicand, f rlf Multiplicand + 1, f decfsz BitCount goto Loop
The code given below is the most ef cient way of doing a 16-bit multiply with a 32-bit result. It is not immediately obvious, but it s very clever. Rather than using a 32-bit add each time the shifted data is detected, it provides a 16-bit add (with valid carry) and then shifts the data down. This code does not change Multiplicand but does change Multiplier. Note that in the code I use a 32-bit value for Product (using a Product:5 line in the CBLOCK variable declare statement).
