2.4
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 DSP engine also has the capability to perform
inherent
which require no additional data. These instructions are
ADD, SUB and NEG.
The dsPIC30F 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
may be used concurrently by the same instruction
(e.g., ED, EDAC).

The DSP engine has various options selected through
various bits in the CPU Core Configuration 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
