how can I start install the design on FPGA

[mouath]

hi ,

i design a system on the labview 8.2 thats detect some parameter of the ECG signal , now i wnat to install the design on the FPGA kit 

kown the input signal is real time ECG  signal .

how can i start doing this ?

what the needed informaton to do that ?

thank you

The question you are asking is rather broad and there are many things you need to consider. To begin with, there are two FPGA platforms that we have. The first one is called CompactRIO and is an embedded controller consisting of an FPGA and an Real-Time controller. The second option is an R-Series card which can be PXI or PCI, and si simply a blank FPGA board which you can customize to your needs. Another important factor that you need to consider is the signals you are dealing with. Since they are ECG signals, I assume that they are analog signals in which case you will need some signal conditinoing and the system you select must have a way to digitize those signals. CompactRIO would be a good solution for this becuase we offer many modules that can perform the signal conditioning that you need.

As far as software you will need LabVIEW and LabVIEW FPGA module. If you decide to use a CompactRIO you will also need LabVIEW Real-Time module to program the Real-time controller.

Hi - I just want to clarify that National Instruments does not make any signal conditioning modules or other products that are designed for direct connection to a human subject (we don't design or certify to the required medical safety standards).  Our products are often used in conjunction with amplifiers or signal conditioners that are designed for these applications that have outputs that are filtered, isolated, and amplified and are ready to be digitized by a DAQ board or other NI product.

If used on animals, these safety concerns are often not as big an issue, but you still need a specialized signal conditioner that has a relatively high gain and balanced differential inputs (with high common-mode rejection) to acquire a good, low-noise ECG signal.  This is similar to a thermocouple type input module, but with more bandwidth than a typical thermocouple module and AC coupling.

Bottom line:  you really need to use a specialized biosignal amplifier that has a single-ended analog output to connect to NI DAQ boards or FPGA boards.
