I wish to use LABVIEW for data acquisition and real-time control applications. In the past I have used data-acquisition cards and run C programs in the DOS mode in an infinite loop. I have tried out using LINUX and real-time versions of LINUX like RTLINUX and RTAI but since my knowledge of LINUX is limited was not able to get far. I am now thinking of using real-time LABVIEW along with a real-time embedded controller and FPGA based data acquisition cards.
I am working in the field of power electronics and particularly power quality. I hope to be able to sample data at 50-100 microseconds. After data acquisition I wish to perform some very basic arithmetic operations within a loop which will be executed 200-300 times between samples. I have heard that the overhead of LABVIEW is considerable and this slows down the system. However I would like to know what would be the response if I use Real-time LABVIEW along with LABVIEW with a 1.2 GHZ processor. The data cquisition and conversion to digital form should be over within 10 microseconds.
Could anyone working in the area of electrical engineering particulalry power electronics tell me their past experience with LABVIEW in their applications?
Thanks and bye, Shivkumar Iyer.
