Has anyone used this idct core from opencores.org?
**broken link removed**
I am using it for my thesis and since I can't find the original programmer I was wondering if anyone from this forum has used it or tested it for a jpeg implementation.

You are right but this is not my code this is a DCT core ready and verified from www.opencores.org and I am trying to synthesize it in order to adjust it to my project. That's why I am asking. Perhaps someone has encountered this kind of typecasting and has a solution to propose.
signed to std_logic_vector
I need to synthesize a DCT core to a Spartan3E FPGA and have the following problem:
The core uses a Rom for the DCT coefficients and calculates them like this.
type ROM_TYPE is array (0 to (2**ROMADDR_W)-1)
of STD_LOGIC_VECTOR(ROMDATA_W-1 downto 0)...
I desperately need the mips-elf-gcc tools and the sparc-elf-gcc tools for Archc2.0. The download page is this Archc Compilers but the server seems to be down from this morning and I could get no response from the website support. Does anyone have them downloaded and can he/she upload the files...
I am afraid the only software I have available to use is microwave office. Does it have this option as well?
Can someone who has ADS help me and post the admittance here?
The spice model for An2221 is :
Q2N2221A NPN ( IS = 426.3f XTI = 3.0 EG = 1.11 VAF =250.3 BF = 72.14 ISE = 48.14p
+ NE =...
How can I calculate-simulate the input output admittance of a BJT transistor in various frequencies? The Datasheet doesn't include the information I need.
I need to use an RFC inductor in the following circuit:
**broken link removed**
How can I calculate its value? This is an 30Mhz RF 5MHz IF mixer.
Then I have to use one again for the same mixer working at 100Mhz RF 10,7Mhz IF. Will 1uH be enough? How can I justify the chosen value?
In the...
In my microwave nonlinear library I have only GBJT models with 4 pins.
But the 2n221A transistor has 3 pins. When I try importing this model in microwave using the way suggested I get a 4 pin trandistor. Can I use it? How will I connect the forth pin.
Can someone please send me or upload here...
serial write labview
Thanks to you all for taking the time to reply.
The problem was solved. I was using the student version which does not include the VISA drivers. So all I had to do after all was download and install the VISA software which was not included.
If someone else needs to...
labview visa serial
I am using Labview 8.2 to communicate with a microcontroller using serial write/read (at least I am trying to...).
I open the example file "Basic_Serial_Write_and_Read.vi" and as soon as I press "Run" the following error appears:

gbjt in microwave
I have a project where I need to make an RF mixer using AWR Microwind.
The first thing I noticed is that this tool doesn't include in the given libraries the elements that I need.
I have to make a mixer using a BJT transistor. My mixer has to be based on the mixer suggested...
