Cpu Design Questions
The main difference between a superscalar architecture and a vector architecture lies in their approach to parallelism and instruction execution.
Superscalar architecture focuses on instruction-level parallelism, where multiple instructions are executed simultaneously by employing multiple execution units within the CPU. It allows for the concurrent execution of multiple instructions from a single thread, exploiting instruction-level parallelism by dynamically scheduling and executing instructions out of order.
On the other hand, vector architecture emphasizes data-level parallelism. It operates on vectors or arrays of data elements, performing the same operation on multiple data elements simultaneously. Vector architectures are designed to efficiently execute operations on large sets of data by utilizing vector registers and specialized vector processing units.
In summary, superscalar architecture targets instruction-level parallelism by executing multiple instructions concurrently, while vector architecture targets data-level parallelism by performing operations on multiple data elements simultaneously.
