The dsPIC33FJXXXGPX06A/X08A/X10A ALU is 16
bits wide and is capable of addition, subtraction, bit
shifts and logic operations. Unless otherwise men-
tioned, arithmetic operations are 2’s complement in
nature. Depending on the operation, the ALU may
affect the values of the Carry (C), Zero (Z), Negative
(N), Overflow (OV) and Digit Carry (DC) Status bits in
the SR register. The C and DC Status bits operate as
Borrow and Digit Borrow bits, respectively, for subtrac-
tion operations.
The ALU can perform 8-bit or 16-bit operations,
depending on the mode of the instruction that is used.
Data for the ALU operation can come from the W
register array, or data memory, depending on the
addressing mode of the instruction. Likewise, output
data from the ALU can be written to the W register array
or a data memory location.
Refer to the “dsPIC30F/33F Programmer’s Reference
Manual” (DS70157) for information on the SR bits
affected by each instruction.
The
incorporates hardware support for both multiplication
and division. This includes a dedicated hardware
multiplier and support hardware for 16-bit-divisor
division.
3.5.1
Using the high-speed 17-bit x 17-bit multiplier of the DSP
engine, the ALU supports unsigned, signed or mixed-sign
operation in several MCU multiplication modes:
1.
2.
3.
4.
5.
6.
7.
3.5.2
The divide block supports 32-bit/16-bit and 16-bit/16-bit
signed and unsigned integer divide operations with the
following data sizes:
1.
2.
3.
4.
The quotient for all divide instructions ends up in W0
and the remainder in W1. 16-bit signed and unsigned
DIV instructions can specify any W register for both the
16-bit divisor (Wn) and any W register (aligned) pair
(W(m + 1):Wm) for the 32-bit dividend. The divide
algorithm takes one cycle per bit of divisor, so both
32-bit/16-bit and 16-bit/16-bit instructions take the
same number of cycles to execute.

The
17-bit x 17-bit multiplier, a barrel shifter and a 40-bit
adder/subtracter (with two target accumulators, round
and saturation logic).
The dsPIC33FJXXXGPX06A/X08A/X10A is a sin-
gle-cycle, instruction flow architecture; therefore, concur-
rent operation of the DSP engine with MCU instruction
flow is not possible. However, some MCU ALU and DSP
engine resources may be used concurrently by the same
instruction (e.g., ED, EDAC).
The DSP engine also has the capability to perform
inherent accumulator-to-accumulator operations which
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 Control register
(CORCON), as listed below:
