The
dsPIC33FJ16MC304 features a 17-bit by 17-bit single-
cycle multiplier that is shared by both the MCU ALU
and DSP engine. The multiplier can perform signed,
unsigned and mixed-sign multiplication. Using a 17-bit
by 17-bit multiplier for 16-bit by 16-bit multiplication not
only allows you to perform mixed-sign multiplication, it
also achieves accurate results for special operations,
such as (-1.0) x (-1.0).

The
dsPIC33FJ16MC304 supports 16/16 and 32/16 divide
operations, both fractional and integer. All divide
instructions are iterative operations. They must be
executed within a REPEAT loop, resulting in a total
execution time of 19 instruction cycles. The divide
operation can be interrupted during any of those
19 cycles without loss of data.
A 40-bit barrel shifter is used to perform up to a 16-bit
left or right shift in a single cycle. The barrel shifter can
be used by both MCU and DSP instructions.
