超标量和VLIW [英] superscalar and VLIW

问题描述

我想问一些有关ILP的问题.

I want to ask some questions related to ILP.

• 超标量处理器是标量处理器和矢量处理器的混合体.那么我可以说向量处理器的体系结构遵循超标量吗?

• A superscalar processor is sort of a mixture of the scalar and vector processor. So can I say that architectures of vector processor follows super-scalar ?

同时处理多个指令不会使体系结构成为超标量，因为流水线，多处理器或多核体系结构也可以实现这一目标.这是什么意思?

Processing multiple instructions concurrently does not make an architecture superscalar, since pipelined, multiprocessor or multi-core architectures also achieve that. What does this means?

我读过超标量CPU体系结构在单个处理器中实现了一种称为指令级并行性的并行形式"，超标量不能使用多个处理器吗?谁能提供使用超标量的示例?

I have read ' A superscalar CPU architecture implements a form of parallelism called instruction level parallelism within a single processor', superscalar cant use more than one processor ? Can anyone provide me example where superscalar are used?

VLIW ，我在这里浏览了这篇文章是第9页上的图4，它显示了通用的VLIW实现，没有复杂的重排序缓冲区以及解码和分派逻辑.术语不解码"使我感到困惑.

VLIW , I have go through this article there is figure 4 on page 9.It shows a generic VLIW implementation, without the complex reorder buffer and decoding and dispatching logic. The term without decoding is confusing me.
