Hello,

i am doing in this week a task for a subject of the university about Superscalar Computers and
Superpipelined architectures.

I post this question here wishing that anyone can answer it XD.
I know that is a hard question, and some friends Engineers couldn't give me the response.

"What is the difference between a Superscalar Computer and a Multicore computer in the
instructions processing?"

I understand the basic idea that a multicore has multiple cores and they can process parallel data,
but a superscalar treats some instructions at same time, being then parallel computing too.

I have the answer of my own question (i post it for if anyone wants to learn a bit more of
computer architectures Smile

A superscalar processor uses the same cache and TLB to any thread. A multicore processor
has some caches (one by processor).

In this sense, a multi-core processor can be also superscalar, doing some instructions of one thread
and having cache-independence from the other cores.

NOTE for Admins: This thread can be closed Smile

Did you try turning it off and on again?

Or simply Google! Very Happy
