"F" Stands for Features and Even More Flexibility As FPGAs Continue to Evolve

Field programmable gate arrays (FPGAs) are no longer unique in military designs—they are used everywhere. But far from being used merely as a hunk of highly integrated glue Read More...

FPGAs Flex Their Processing Muscles

In the past, FPGAs were not a viable option as offload engines or as co processors because of relatively low complexity/performance and insufficient embedded memory. Moreover, becRead More...

Solving Timing Closure in High-End FPGAs

FPGA design sizes have reached unprecedented levels with million gate parts becoming increasingly common. FPGAs lead the rest of the industry in employing the most cutting-edge faRead More...
