Virtual CPU

[Al Murphy]

Folks,

Hope I have the right group here but what does anyone know exactly
what a virtual CPU is?

Cheers,
Al.

A virtuous CPU? That would be a CPU that didn't cuss, smoke, drink, or
mess around.

<slap> sorry...

Probably what was meant is a CPU that is instantiated in an ASIC or
FPGA, rather than as a real, hold-in-your-hand CPU. For some examples,
click over to http://www.opencores.org.

"The brand new intel 3.06GHz CPU features intel's brand new
"hyper-threading" technology, which allows the CPU to perform multiple
proccessor operations, by way of creating a "virtual CPU". Although this
technology doesnt give better performance under single program operations,
it offers some outstanding results when running multiple CPU intensive
programs." [

Found the above after a google search. There are probably more meanings
depending on the context.

Could be a software simulation/emulation of a CPU. The simulation software
embraces the CPU instruction set and allows one to test user software
without actually using the CPU in question. Works pretty well, by the way,
until one gets into the realm of tricky hardware interrupts and similar
issues.

Or do you mean "Virtual Machine", IBM's VM system:
