3.6
The
dsPIC33FJ64MCX02/X04
dsPIC33FJ128MCX02/X04 ALU is 16 bits wide and is
capable of addition, subtraction, bit shifts and logic
operations. Unless otherwise mentioned, arithmetic
operations are two’s complement in nature. Depending
on the operation, the ALU can 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 subtraction 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
dsPIC33FJ64MCX02/X04
dsPIC33FJ128MCX02/X04
hardware support for both multiplication and division.
This includes a dedicated hardware multiplier and
support hardware for 16-bit-divisor division.
3.6.1
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:
• 16-bit x 16-bit signed
• 16-bit x 16-bit unsigned
• 16-bit signed x 5-bit (literal) unsigned
• 16-bit unsigned x 16-bit unsigned
• 16-bit unsigned x 5-bit (literal) unsigned
• 16-bit unsigned x 16-bit signed
• 8-bit unsigned x 8-bit unsigned

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.
3.7
The DSP engine consists of a high-speed 17-bit x
17-bit multiplier, a barrel shifter and a 40-bit
adder/subtracter (with two target accumulators, round
and saturation logic).
The
dsPIC33FJ64MCX02/X04
dsPIC33FJ128MCX02/X04 is a single-cycle instruction
flow architecture; therefore, concurrent operation of the
DSP engine with MCU instruction flow is not possible.
However, some MCU ALU and DSP engine resources
can be used concurrently by the same instruction
(e.g., ED, EDAC).
The
accumulator-to-accumulator operations that require no
additional data. These instructions are ADD, SUB and
NEG.
The DSP engine has options selected through bits in
the CPU Core Control register (CORCON), as listed
below:
• Fractional or integer DSP multiply (IF)
• Signed or unsigned DSP multiply (US)
• Conventional or convergent rounding (RND)
• Automatic saturation on/off for ACCA (SATA)
• Automatic saturation on/off for ACCB (SATB)
• Automatic saturation on/off for writes to data
• Accumulator Saturation mode selection
A block diagram of the DSP engine is shown in
