    Minimum Order of FIR Filter

    Well, fc is cut frequency of the filter. The most important thing is you gain phase linearity in FIR filters, at the cost of larger degree. Besides, they're so easily implemented with Multiply and Accumulate blocks and a Tapped Delay Line. They are feedforward and that makes their...

    how i can convert the color image into gray image using vhd

    Re: how i can convert the color image into gray image using It's however in some format, isn't it? If it's digital, it's RGB or YUV or YCbCr or ....

    IIR Filter in fdatool

    for IIR Filters matlab would export a filter "object", which is simply a struct with multiple fields, two of which are numerator and denom.

    VHDL CODING STYPE FOR STATE MACHINES.

    Well in fact with the second type, you are defining the "state coding" of the state machine. The states should be converted to binary signals when implemented, and you are defining how to do that. If you don't the synthesizer would do that job. Usually they have options for that, and the default...

    Two-way car alarm systems.

    Does anybody now if there is any standard for two-way cr alarm systems (those that have pagers)? If not, what frequency/modulation/bandwidth/... they use usually?

    New to EDK...Guidance needed

    Go and see xilinx free courses. Lots of VERY useful documents there. http://www.xilinx.com/support/training/free-courses.htm

    find maximum number in an array

    First, maybe you could rewrite your function with Symbolic toolbox, and that would be able to find the maxima/minima. Second, the algorithm you tried to explain is a gradient-descent algorithm (or Conjugate Gradient algorithm). You could easily find data on it in MATLAB, and most probably...

    VHDL Simulator related Query

    Of course you could do it with ModelSim too. You would have to know TCL and read ModelSim documents carefully to understand the automation process. It also doesn't need Writing TextIO VHDL testbenches and could easily export well-formatted outputs. But for image, sorry, no special library etc is...

    random number generator

    just design an LFSR, and use 2 bits of it. Of course it depends on that how random your result should be. If you need more unpredictable design, then you should find some better generator.

    Connecting two embedded systems using Bluetooth USB Dongle?

    Re: Connecting two embedded systems using Bluetooth USB Dong I don't know what sort of embedded system you want to use. First of all, there are microcontrollers there with a usb host integrated. Second, you could easily use usb host interface chips, like those from cypress. Then you'll be able...

    Video controller IP and PowerPC 405

    locallink powerpc 405 I just know that xilinx doesn't have any specific documents on generating peripherals using DMA (the PLBV46 migration document says you should see DMA migration chapter, which is non-existent). This is a problem I have too. But I think for this to happen, in PLBV64...

    DDR SDRAM Interface with Microblaze in EDK

    Interrupt of what peripheral? Each peripheral has its own drivers, including interrupt management functions.

    find maximum number in an array

    Well, first of all what language is to be used? Or maybe hardware??? If matlab, use max! but that should not be your problem, is it?

    Is OFDMA for mobile communication only?

    OFDMA and OFDM are not exclusive to mobile or fixed. OFDMA is defined in 802.16.2004 besides OFDM for fixed wireless, and both are being cosidered (maybe standardized) for mobile. MIMO a feature added to any communications system, so that spatial redundancy is used for better performance, and...

    Hard-RT Systems, is it possible to make guaranteed deadlines

    Re: Hard-RT Systems Hi Something that matters a lot is how you're system is going to work: event-driven or time-driven. If event-driven, nobody can't gaurantee the system unless its too simple. That's simply because unknown conditions in events can happen, which is not in control and they...
