Info on unified memory architecture

Info on unified memory architecture

(OP)
Need some information on the unified memory architecture. What is the puppose and functionality ? How does this incorporate into today's world ?

RE: Info on unified memory architecture

Hi,

I bet your long gone, not having had an answer for so long. But if you do pop by here is my answer to your post.

Most PCs use two (not including processor cache here) types of RAM. One is on the mother board and is used by the processor for programs, variables etc. The other memory is on the Graphics card.

Recently (within the last few years) PCs have been coming out with much of the peripheral functions built into the motherboard, such as sound, ethernet and Video, instead of the plug in cards we are used to. ( I don't like them incidently - all your eggs in one basket sort of thing).
Their advantage being that they're cheaper.

Now a motherboard with a built in Graphics processor tends to share the motherboard memory between the CPU and the Graphics processor. this memory would be known as unified memory architecture ie. one memory different functions.

I bought my youngest son such a machine and it is noticeably slower than his brothers, who has a seperate graphics card and memory. The reason for it being slower is that you have 2 processors asking data from one memory. At some point you'll get both asking at the same time. Somone has to wait !.

So in short the motherboard memory is shared between the CPU and the onboard Graphics Processor.

Regards

Hi there,
I'm doing an assignment on Unified Memory Architecture but didn't understand what it was about, the information you have provided has be of much help, i'm not the origional person who asked for the information but thank you all the same.
Regards

RE: Info on unified memory architecture

Heres a little info if ur still there, this made it easy for me to understand along with the info Laffalot provided.

Unified Memory Architecture is a computer that has graphics chips built into the motherboard that use part of the computer's main memory for video memory is said to have Unified Memory Architecture.
