it's Ok I was think of the same thing tho today for instance with a for loop
instead of using pure binary in the for $loop (you) { could use the "Grey Code"
which would make the the amount of logic switching less }
Grey code
00 only one state change here
01 only one state change here
11 only one state change here
10 only one state change here
pure binary
00
01 from this to
10 this you have to change two states
11
ect...
for $loop (1..4) { print "this for loop could be speed up by using the Grey code
instead of pure binary" }
:}

Apologize Mark for sending you down the hardware path with the VHDL descriptor.
A modeling language is not related specifically to hardware, I was just trying
to illustrate that they are for designing a solution at a higher level than the
implementation language. VHDL was simple to explain in this regards since there
is a definite break between the design of the algorithms and the implementation
on to the hardware.

Then your talking about a JTag or a USB script
most of those are only using C or ASM or VHDL program
makes me think of the 552 FPGA's I just bought
It would be nice to use perl in such a way I think it would really
help in the learning curve your right , C has a lot memory
things that you have to get right or the code doesn't work
perl is more forgiving , on windows tho I think you would have
to go threw WMIC to get that kind of functionality so its
not just perl code you have to use the WMIC inside the perl code I think..
I have been trying to figure out how to do that...
the best way i can think of is C implementation module for perl
but there are so many different chips , that you have to have a logic
design knowledge first , then you have to have the data sheets
then you have to know the protocols for the operating system
it would be nice to use some shift registers chips with the USB
in perl , I think that is the first place to start with some 7495 chips
and just get some data loaded onto it from the USB ...
this is something I hope to accomplish by the end of this year
I have tried before to find USB how to's and not one for perl yet
except for a toy missile launcher in Linux...

UML is to OOP as ERM is to database design.

Going by memory - and at my age it starts to get fuzzy - UML -> unified
modeling language, similar in terms of VRML, PMML, VHDL, and other
modeling/design specification languages to specify an algorithm that is used to
implement a solution. In most cases it is some type of a compiler that outputs
to a target. In the case of VHDL you define the logic for a hardware design and
it can be sent to a specific programmable logic device (in the generic term). I
am sure Google has a number of hits.

If you have ever tried to load all the modules that you use and build a
.exe like a PDL.exe I Have noticed that it takes so long it is not worth
the effort
in that the purpose of a module are to keep the software lite weight so as
to run fast
as modules accumulate the loading start up seems to be effected
dramatically!
I have done a very large 66 gigabyte project with compression
routines(that I developed)
that transformed the data into 3.6 gigbytes of data, with perl in about
11hours with
2.4 ghz x4 CPU's running full speed ... I can Load that data now
in a fraction of a second and use mapping (that I developed) into about
40 Megabytes of Ram .. now I can search threw that 60 gigabyte database
for a sequence in seconds and can get a match or the match is not there
so that being said the software is good ... but you have to use many ideas
in many different way to achieve your success ...
as far as commercially speaking I would never use database software
developed by any one other then me and my company,
so that way only you and your company know how to use the software
this make data safer in the long run for clients for the company
and for the internet ...

Hi,
I have a lot of literature about Perl and I see that up to advanced
material potentially related to very large projects, there is not a single
attempt (it seems) to leverage UML (or similar tools) to organize the job as a
part of the learning.
Perl is both fun and powerful, but the flattened landscape Perl , Regex,
DBI, LWP, PDL, XML, and so on and on, can become to seem an enumeration not
suggesting a process to determine a mapping (or more alternatives to choose in)
between a goal and the resources available.
Some people here manage large projects and could they tell their thinks on
this?
Thanks
