A digital signal processor (DSP) is design to perform FFT operstions for a digital oscilloscope that utilizes a 12 bit A/ D Converter. The most cost effective ALU architecture for this CPU is a:
a. Fixed -point multiplier with an 8 bit data path.
b. Floating -point multiplier with an 8 bit data path.
c. Fixed -point multiplier with an 16 bit data path.
D. Flaoting -point multiplier with an 16 bit data path.
