Special MCU Features
The dsPIC33FJ32GP302/304, dsPIC33FJ64GPX02/
X04, and dsPIC33FJ128GPX02/X04 features a 17-bit
by 17-bit single-cycle multiplier that is shared by both
the MCU ALU and DSP engine. The multiplier can per-
form 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 dsPIC33FJ32GP302/304, dsPIC33FJ64GPX02/
X04, and dsPIC33FJ128GPX02/X04 supports 16/16
and 32/16 divide operations, both fractional and inte-
ger. 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.
