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 archi-
tecture, threfore, 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).
