Cpu Design Questions
The main difference between a scalar architecture and a parallel architecture lies in how they process instructions.
In a scalar architecture, the CPU executes one instruction at a time, operating on a single piece of data. It follows a sequential approach, where each instruction is completed before moving on to the next one. This type of architecture is suitable for simple tasks and does not take advantage of multiple processing units.
On the other hand, a parallel architecture involves the simultaneous execution of multiple instructions or operations. It utilizes multiple processing units, such as multiple cores or processors, to perform tasks concurrently. This allows for faster and more efficient processing of complex tasks, as different instructions can be executed simultaneously. Parallel architectures are commonly used in high-performance computing systems and applications that require heavy computational power.
In summary, the key difference between scalar and parallel architectures is that scalar architecture processes instructions sequentially, while parallel architecture processes instructions concurrently using multiple processing units.
