2.5
The dsPIC33F ALU is 16 bits wide and is capable of
addition, subtraction, bit shifts and logic operations.
Unless otherwise mentioned, 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 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 reg-
ister array, or data memory, depending on the address-
ing 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 dsPIC33F CPU incorporates hardware support for
both multiplication and division. This includes a dedi-
cated hardware multiplier and support hardware for
16-bit-divisor division.
2.5.1
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.
2.5.2
The divide block supports 32-bit/16-bit and 16-bit/16-bit
signed and unsigned integer divide operations with the
following data sizes:

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 algo-
rithm 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.
2.6
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 dsPIC33F is a single-cycle, instruction flow architec-
ture; therefore, concurrent 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:
