SIMD vs Vector Processing: What Is the Difference?
SIMD and vector processing overlap, but they are not always interchangeable terms. This guide separates fixed-width packed SIMD from richer vector-length-based execution models.
Research
Processor architecture becomes easier to understand when individual mechanisms are connected to the larger problem they are trying to solve.
What Is a Superscalar Processor?
A superscalar processor can issue multiple independent instructions during the same cycle. Learn how fetch width, renaming, scheduling and execution resources make that possible.
What Is a Vector Processor?
A vector processor applies one operation across many data elements using vector registers and vector instructions. Here is how the model works and why it still matters.
