Why Are There No Fir Filter Programs For Mac

Hi everybody, I'm working on a small project in which we want basically to filter Input data (Input Data Rate = 105Mhz) with a FIR filter (64 coefficients). I've forseen to use the MAC FIR IP provided by Xilinx but there could be a problem in the way input data are sampled. Indeed, MAC FIR IP provides an output named RFD(Ready For Data) which indicates when the MAC FIR can accept new data. Does that mean ND (New Data signal) can't be stay at '1' to put new data in FIR at each rising edge of clock sample (105 MHz)? Since my Input data flow is unbroken, how can I do to process this flow in real time?

Is there other free FIR IP more suitable for my application? Thank you in advance for your answers. PS: I'm a french guy, so I hope my english is not too bad and you will able to understand what I mean.:oops.

HiI'm working on a small project in which we want basically to filter Input data (Input Data Rate = 105Mhz) with a FIR filter (64 coefficients). I've forseen to use the MAC FIR IP provided by Xilinx but there could be a problem in the way input data are sampled. A MAC FIR is not ideally suited to your application, given those parameters. At a clock rate of (say) 210MHz, you would need 32 parallel MAC units to keep up with the data input rate. This is virtually a full-parallel FIR implementation.

Of course your achievable clock rate will depend on what part you are targeting. You should probably still be able to use the Xilinx core, as it is capable of using multiple MAC units according to your data rate requirements. Provided that you configure the core such that it has enough processing power to keep up, the handshaking on the data input samples will cause you no problems. Cheers, -Ben. You can do this very easily for the cost of $595 US. Just buy a Xilinx ML-403 board, and a couple of 32x3.100' connectors to get the data in and out of the board.

The XC4VSX35 fpga on the card has 192 hardware multipliers and adders, arranged in 2 columns of 96 each. One column should suffice for your requirements, and it will run as a 96 tap FIR filter at 400 MHz. Getting data in & out at 400 MHz would probably require using LVDS, but 105 MHz should be relatively easy using CMOS 3.3V or other single ended signaling.

You'll probably spend more time getting the IO timing right than on the FIR filter, which can be generated as a monolithic core by the Coregen tool. You really don't want to use the MAC FIR, by the way. Just a standard FIR will work fine.

Iowa Hills Free Software Download Page Iowa Hills Software Digital and Analog Filters Program Download These programs are free. We just ask that you report any mistakes you find using the email address given in the About menu. To Download and Install These Programs. Download the zip file. Open the zipped folder with Windows Explorer, go to Files menu, click on Extract All.

Windows will create an unzipped folder with the same name as the zipped folder. The program is now ready to run. Note: Windows will not execute a program from a zipped file, so the entire folder must be unzipped. These programs don't use an installer.

They use the Windows 95 method of 'installation'. In other words, download the zip file, extract the contents, and create your own shortcuts. Nor is there an Uninstaller.

On 5/7/16 we replaced a look up table with code to generate the second order S plane coefficients for the various low pass prototype filters.

We also added an FIR frequency sampling algorithm. FIR Filters On 10/13/16 we added a custom FIR filter option.

The user can define the desired magnitude response in a text file for the program to read in. See the directions in the Help file. An example file is given. P51 Root Finder On 9/23/16 we updated the P51 root solver again to fix a premature deletion of the array P. On 9/12/16 we updated 2 lines of code in the quartic root solver.

Lines 53 and 60 could cause the array index to go out of bounds depending on the input array size and how the compiler optimized the code. IIR Filters On 5/3/16 we updated the IIR program with an improved Elliptic filter algorithm. We also added the Classic L (Papoulis) prototype and added the ability to change the gain of the filter. On 10/20/16 we added a simple note to the coefficient tables to remind users that some DSP cores require -a values from those generated by the program.

Filter Polynomials On 5/3/16 we updated the Filter Polynomials program with an improved elliptic filter algorithm and fixed a couple of minor problems. Op Amp Filters On 12/1/15 we updated the op amp filter program to include all pass filters. Smith Chart On 10/26/15 we changed the schematic to show the source on the left side, and the load on the right, which is a more typical way these are shown. You can help by reporting mistakes. These programs can of synthesize millions of possible filters, so it's impossible test every possible filter configuration.
