Selection of processor for high speed data

Hello all,
I am in the process of selecting a processor. I have few queries
related with the selection of a processor for embedded systems
design . For selecting the correct processor to handle high rate of
data, is there any mapping/logic between the processor clock speed and
the rate in which the data enters the processor . That is, consider
that the data comes in at the rate of 1Gbps in the input port of the
processor. What is the possible clock rate that the processor should
operate/support to handle the data ? If there is an external memory/
RAM requirement, how much memory should be there for that particular
processor clock frequency for that particular speed(1Gbps) of input
data and what is the logic to determine that ? How does the number of
bits of processor play a role in the selecting a processor to support
high speed data(1Gbps) ? Does internal memory/cache also have any role
in taking the decision . If Yes, how to determine the amount of such
memory for this high speed data(1Gbps) ? Are there other factors ? In
general, i need the a table of these factors mapped against various
other factors or the clear method/logic of determining it so that it
can be considered to select a processor for processing high speed data.

How much entropy?

What do you expect to extract/preserve from said data (a modified
version of my previous query)?

See above.

How many cylinders does a vehicle need to transport a
5,000 pound payload?

Should the tires on said vehicle be whitewalls, blackwalls or
white-mounted-black?

Should the vehicle burn gasoline, diesel or some other fuel?

You're asking questions expecting *specific* GENERALIZATIONS
(an oxymoron?) that don't easily apply...

Think about the nature of the data and what you expect to *do*
with it before you set out in search of the "right" processor.
(e.g., do you have budgetary constraints?  size? power? etc.)

No Budgetary/Size/Power constraints.

How fast doesn't address how much. Is it a continuous stream or is it in
packets? How are the packets structured (envelope, addressing, data
content, compression, encoding, CRC, hashing, error recovery, etc.)?

Step 1. Define the problem.
Step 2. ???
Step 3. Profit!

If you have no budgetary, size or power constraints, then I'd recommend 
hiring someone who understands what you are dealing with.

Alternatively, buy an embedded PC card with an i7 processor - it's 
probably going to be fast enough and will save you the effort of trying 
to understand what you are trying to do.

Hello super stupident.
Good bye and go do your homework.

Ah, then you have no need for all of this pesky data/tables!
Just buy the biggest, fastest, most expensive machine you can
find!  Problem solved!

Next question...

Vladimir Vassilevsky is idiot.
