    operating @ high frequency with xilinx cores on virtex 6 FPGA

    Hello; I want to ask a few questions about performance of FPGA cores at high clock frequency. I'm trying to operate my system at 500 MHz. I will use FFT core, dds core, FIR filter core of xilinx with my system. I can generate a system with the cores at 500 mhz succesfully on ISE 11.5; but I...

    I want to use the ADC on spartan 3e kit.

    thank you for the answers, Jack//ani I am trying to implement a SPI interface to read ADC values but I couldn't be succesful. I don't want to use picoblaze. If anybody have VHDL code for the ADC - SPI interface, I will be very glad. please help me... thanks...

    using spartan 3e starter kit as stepper motor driver

    Thanks for your answer, mrflibble. Now I want to ask you another question. How can I connect stepper motor to FPGA? I couldn't find an interface circuit for FPGAs. It should be different from the circuits using with microcontrollers. Thanks again...

    using spartan 3e starter kit as stepper motor driver

    spartan 3e stepper motor Hello; I want to control a stepper motor with spartan 3e starter kit. I have found a source code to control the motor with XC2C32A CPLD at xilinx website. There is a XC2C64A CPLD on the spartan 3E. I'm not sure if I can use the code safely for the spartan 3E. If there...

    I want to use the ADC on spartan 3e kit.

    Re: ADC on spartan 3e thank you very much for your help now I'm trying to find the maximum input voltage range of the ADC on spartan3E starter kit. According to the datasheet it seems 1.25v but this is a very small range I think Is there anyone know the range of the ADC? Thanks

    FPGA and DS18B20 sensor reading

    Hello, This is a very old subject, but maybe you can answer to my question. I want to connect a DS18B20 temperature sensor to Spartan 3E starter kit but I'm not sure if I should use an external pull-up resistor as mentioned in DS18B20 datasheet for microcontrollers or connect throughly without...
