    How EP3C25F256C7N work?

    Digital systems are designed using two different approaches. The first approach is known as the sequential approach and employs microcontrollers and microprocessors for data processing and data communication. The second approach is the parallel approach which utilizes FPGAs and ASICs for high-performance computing.

    FPGAs technology has advanced a lot in the recent past and can now be used to implement SoCs (System on Chip). In an SoC, the microcontroller and the associated digital circuits are housed in the same device package. This offers the benefits of high performance, high efficiency, low power consumption and low cost. Customized SoCs can be used for a wide variety of applications such as video processing, signal processing, industrial control and biomedical applications. The parallel operation of FPGAs makes them faster and superior to the traditional microcontrollers.
