Arbitrary Clock Frequencies From Base Clock
I have a board with the Xilinx V2 Pro (xc2vp30). I am designing a BPSK
demodulator on this board. For the demodulator, I need to generate
arbitrary clock frequencies from 8 MHz to 10 MHz in 100 kHz increments
from the base clock. How can I do this? Does anyone have any VHDL code
I can use for this?
Thanks and regards,
I do this using this simple Numeric Controlled Oscillator -NCO- code I
found in here: http://www.analogservices.com/vhdlmod.htm
However the generated clk is not pure in the sense that some periods
are a bit longer than others.
abhisheknag@gmail....binary stream with vector of '(unsigned-byte 8)
I am using vectors of '(unsigned-byte 8) to read/write data from/to
sockets. The software interface I have to use implies the use of such
vectors, and I don't have access to underground binary stream nor to
the socket itself.
Since I didn't found any simple/portable method to make a binary-
stream to read/write data , I am using adjustable vectors with the
fill-pointer and vector-push-extend functions. But I didn't found any
standard functions to read from a vector without using an explicit
offset each time. Did I miss domething interesting there ?

I need use in signal handler function some data structure, but I dont know
I have something like this:

in my Signal() implementation ; it gives me that signal handler function

First is siginfo_t structure pointer but i dont know what type is secound ?

Next problem is how to copy or point data structure , which i want to give
my signal handler function,

----- Start Quotes -----
Windows ME and Windows XP have a handy System Restore feature, which
periodically make backups of key system files, especially when you install
new software or hardware. Unfortunately, virus-infected files can get backed
up by System Restore. So, you could clean your system and then roll back to
a restore checkpoint and poof! The virus is back.
Depending on how you feel about System Restore's benefits vs. the risks of
bringing a virus back, you might want to disable System Restore

It belongs to a friend, and everything works, including beaming, and a

Hi There, We have an issue on our db2 restores. We do database dumps
every night, and restore them to development servers every morning.
This works fine with no errors. However if we backup those images to
tape using Veritas netbackup, and then restore those images and try to
restore them to the database, we get "The backup image is corrupt". If
we run db2ckbkp against that image we get "Unable to decompress image
from different platform".
This is really urgent as our backups are currently useless to us if we
cannot restore them properly. If anyone has even a smal...Cable return path has outside signals at 22mhz
In our return plant that we are starting to implement, we are seeing signals
in and around 22mhz. Does anyone know of a way of isolating the ingress
point they must be coming in at. Seems they are some form of radio
navigation signal, as it sounds like a beacon when you use a communication
analyzer to look at the signals.

I am extremely sorry for posting a question that is not

My question is that, I want to retrieve the information about all

some type in my C program and then I compile it to get the elf binary.
Now, can I get the information about that structure (names of all the
fields used in that structure, their type etc) from the elf binary. I

I'm not sure if this is VHDL or Modelsim issue (other than operator
issue), so I'm posting in both groups. It looks like too simple a case
to ask someone online, but I've been scratching my head too long on
this. I'm relatively new to VHDL (and Modelsim as well).
In a testbench, I'm doing a simple signal generation :
- assert 'sig1' at a rising edge of a free running clock at some point
- deassert 'sig1' at the next rising edge
- and on the 3rd edge, do some checking, and so on...
However, the simlation waveform shows that 'sig1' is asserted from...Disk utility

The first thing would be to describe the problem you're trying to solve
