DARPA wants modular chips for its killer robots

Each chiplet would perform a specific function like data storage, computing and signal processing. Those could then be assembled in a mosaic configuration on an "interposer," or tiny circuit board, to perform specific functions. In addition to making it easier to design and add logic to robots, drones and other machines, the devices would potentially be faster and more efficient, since the overall circuit size is smaller. Another problem DARPA's trying to solve is the cost and complexity of intellectual property (IP). Using a standard circuit board often requires the manufacturer to buy multiple patent licenses for unneeded functions.
