SIMD-What is the underlying architecture?

[123elctro]

Which architecture like von Neumman or Modified Harvard Architecture is better for SIMD operations and why?

 

[Ishaan Karnik]

I would say Harvard architecture would be better for SIMD. SIMD is particularly applicable for Digital Signal Processing tasks like computing FFT, adjusting the contrast in a digital image (Image Processing) or adjusting the volume of digital audio (Speech Processing) where computers with multiple processing elements perform the same operation on multiple data points simultaneously.
DSPs generally use Harvard architecture.
