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 operations, in
the form of single instruction iterative divides. The fol-
lowing instructions and data sizes are supported:

TABLE 2-1:

The DSP engine consists of a high-speed 17-bit x
17-bit multiplier, a barrel shifter, and a 40-bit adder/sub-
tracter (with two target accumulators, round and
saturation logic).
The dsPIC30F devices have a single instruction flow
which can execute either DSP or MCU instructions.
Many of the hardware resources are shared between
the DSP and MCU instructions. For example, the
instruction set has both DSP and MCU multiply
instructions which use the same hardware multiplier.
The DSP engine also has the capability to perform inher-
ent accumulator-to-accumulator
require no additional data. These instructions are ADD,
SUB and NEG.
The DSP engine has various options selected through
various bits in the CPU Core Configuration Register
(CORCON), as listed below:

selection
which
The divide instructions must be executed within a
REPEAT loop. Any other form of execution (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 Table 2-1 (REPEAT will execute the target instruction
{operand value+1} times). The REPEAT loop count must
be set up for 18 iterations of the DIV/DIVF instruction.
Thus, a complete divide operation requires 19 cycles.
A block diagram of the DSP engine is shown in
