[oc] Multiple processors on one chip?

["Paul McFeeters" <paul.mcfeeters@ntlworld.com>]

Jim,

XAPP 213 from Xilinx is an 8bit Microcontroller. The current record (as far
as the XAPP explains) is 8 copies of the core on one Virtex but as the
design only uses 35 CLBs (8% of a 100K device) I'm sure somebody will end up
putting 16 or more onto a 200K device. Why not try this as your testbench?
Admittedly the core does take two clock cycles per instruction but easy
enough to factor that out of the final results.

Paul

>From Intel (http://developer.intel.com/technology/hyperthread/)

"Intel® Corporation introduced its Hyper-Threading Technology at the Fall
2001 Intel Developer Forum. Hyper-Threading Technology will enable the world
's first simultaneous multi-threaded (SMT) processor. Today's processor
exploits Instruction Level Parallelism (ILP), but mutually exclusive
hardware resources exist. However, by developing an architecture state for
two processors which share a single physical processor's resources, two
programs or threads can execute simultaneously. Thus, one physical processor
looks like two logical processors to the OS and applications."

What I am talking about is something completely different.

The technology I am talking about will use multiple processors that will
give the operating system and applications running thereon the appearance of
running on one processor. But in reality what would normaly be viewed as a
single thread running on one processor is in fact running in fragments
concurrently on multiplt processors.
