2.3
The dsPIC DSC devices feature a 16/16-bit signed
fractional divide operation, as well as 32/16-bit and
16/16-bit signed and unsigned integer divide opera-
tions, in the form of single instruction iterative divides.
The following instructions and data sizes are
supported:
1.
2.
3.
4.
5.
The 16/16 divides are similar to the 32/16 (same number
of iterations), but the dividend is either zero-extended or
sign-extended during the first iteration.

DIVIDE INSTRUCTIONS
Signed fractional divide: Wm/Wn → W0; Rem → W1
Signed divide: (Wm+1:Wm)/Wn → W0; Rem → W1
Signed divide: Wm/Wn → W0; Rem → W1
Unsigned divide: (Wm+1:Wm)/Wn → W0; Rem → W1
Unsigned divide: Wm/Wn → W0; Rem → W1
The divide instructions must be executed within a
REPEAT
(e.g., a series of discrete divide instructions) will not
function correctly because the instruction flow depends
on RCOUNT. The divide instruction does not
automatically set up the RCOUNT value and it must,
therefore, be explicitly and correctly specified in the
REPEAT instruction, as shown in
executes the target instruction {operand value+1}
times). The REPEAT loop count must be setup for 18
iterations of the DIV/DIVF instruction. Thus, a
complete divide operation requires 19 cycles.
Function
Note:
loop.
The divide flow is interruptible; however,
the user needs to save the context as
appropriate.
