Is controllers are related with embedded network??

Designs</font> in markets from communications to consumer and automotive are moving from ASICs to FPGAs due to increasing mask and silicon costs. As ASIC development costs increase, the break-even volume required to justify the expense is also increasing, pushing a larger number of designs into programmable devices. The same market and process dynamics that are causing ASIC costs to increase are also reducing the cost per gate of FPGAs. This boosts the level of integration, leading to larger devices that can support complex system-level applications. Just a few years ago, such applications could only be implemented in ASICs.


When coupled with the fast time-to-market that FPGAs offer, this implementation shift will continue, presenting programmable logic vendors with a huge market opportunity. Even with these trends, there has been, until now, a challenge: a majority of portable designers have implemented their devices using a microcontroller in conjunction with a programmable logic device. They have used the microcontroller to implement the necessary processing, and have programmed the FPGA with additional application-specific features and functions not supported by the microcontroller.
