As chip designs become increasingly heterogeneous and domain-specific, packing a device with one-size-fits-all chips or chiplets doesn't make sense. The key is rightsizing different components based on real workloads, so they don't waste power when there is too little utilization of logic, and so they don't struggle to complete tasks because they are undersized. Jayson Bethurem, vice president of marketing at business development at Flex Logix, talks with Semiconductor Engineering about the ability of eFPGAs to adapt to new security algorithms and threats, changing workloads, and how they can be used to re-route data whenever a problem crops up in a design.
