altera cyclone

1. I need 16 bit bipolar ADC conversion for 4 analog(voltage) signals and storing the digital output in RAM with the record of time instant. Add also 4 DAC

2. Designing a digital processing circuit to perform various arithmetic operations (i.e. summing, multiplying, square rooting etc.) with the stored data in RAM.

3. After that i like to analyze the stored data from RAM to show the maximum, minimum value, positive and negative discrete values of voltage output from ADC.

4. i like to interface a 3 axis digital gyroscope with i2c bus with the FPGA board and store the output data of gyroscope in RAM and display the stored data of RAM in LCD screen.

5. And the most important thing is that i like to design a standalone device, means after dumping the code in the device memory that will don’t require to use any host computer or external CPU.

These are my requirement. so please give me suggestion, which cyclone device is good for me. right now i am using cyclone EP1C12Q240C8n series by (iisc bengalore).

but i want to design standalone device , so like to buy new series of cyclone including nois ii development kit.

Thank you

Any Cyclone FPGA should be good enough for this kind of task. You just need to look for a kit that has ADC and DACs with the specifications you require.

For the I2C interface, as long as you have a kit with a few I/O pins connected to the FPGA it should be fine. You can find a I2C master IP that you can put in the FPGA.

Dear Daixiwen,

i am attaching a pdf document please kindly check this. all the information related to my fpga cyclone kit is given here in chapter 2. so please tell me,

using this cyclone fpga it is possible to design A stand alone device or not?

anther thing is that where i can interface the i2c bus.

please give me some suggestion.

Thank you

It looks like your Cyclone kit has everything you need. You can use some digital I/Os for the I2C bus. As the I2C data pin (SDA) needs to be bidirectional, you will need to use a full 8-bit port just for the SDA signal, but it isn't a problem since you have lots of I/O pins available on the kit.

As you will also need some I/O pins to connect a character LCD you can for example use the buffers like this:

[list][*]U26 1: SDA pin (direction on pin 1, SDA I/O on one of the pins 37,38,40,41,43,44,46,47

[*]U26 2: SCL (can be always configured as an output, of your device doesn't do clock stretching)

[*]U27 1: data for the LCD (8 bits), bidirectional

[*]U27 2: control for the LCD (3 or 4 bits IIRC, outputs only)[/list]

hello,

i need a TFT touch screen where we can display the output result. which cyclone kit has this feature.... 1.

Yes this should be the cheaper option. But it looks like the touch screen option for the DE0 nano is being phased out, so ask before you buy to be sure they have some in stock.

An alternative is the nios ii embedded evaluation kit (http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&categoryno=56&no=372) but it's a bit more expensive. And IIRC it only has 2 analog inputs and outputs.

hello everyone,

i need a cyclone Fpga kit with bipolar 16 bit ADC and DAC, TFT touch screen display, flash memory etc. can anyone suggest me which kit comes with these combine features?
