Honored ContributorPro& Cons using FPGA???
Hello everyone, Can someone pointed out to me what are the pros and cons using fpga compare to microcontroller? What I know is fpga execute our program in paralel order and uc execute the progra...

Honored Contributor --- Quote Start --- I use 3 sensors and later with the data I got, I need to perform calculation (in which I also need trigonometric calculation) for my control. After that the result of the control is gonna actuate a actuator. Given a choice of uc and fpga, which should I use? What critical here is time respond until the system become stable. --- Quote End --- This sounds like a microcontroller task. If sensors are analog voltages, they will need to be analog-to-digital converted; which for an FPGA requires an external component, but exists on a microcontroller. If you are using actuators, then I would imaging your 'speeds' are quite slow. Well within the capabilities of microcontrollers . For example, the STM32F4-Discovery kit is available from ST for free. Its got a 168MHz ARM Cortex-M4 core, with floating-point unit, fast I/O, USB, etc. That may even be overkill. Cheers, Dave
