Flynn's Taxonomy/Architectures

SISD stands for Single Instruction, Single Data, and it represents traditional sequential processing systems.

It is advantageous for simplicity and low cost but limited in performance since it cannot execute tasks in parallel.

SIMD, or Single Instruction, Multiple Data, involves executing one instruction across multiple data points simultaneously.

It is commonly used in applications like image processing and scientific simulations because it efficiently handles vectorized tasks.

While SIMD architectures are efficient, they require data to be in a specific format, which can limit their general-purpose applicability.

Modern SIMD architectures are seen in GPUs and specialized processors designed for parallel computation tasks. SISD, by contrast, is now primarily found in older or low-power devices like embedded systems and microcontrollers.
