You can understand hardware design and software design, and develop relevant skills. Such expertise allows one to take upon projects that would be harder for CS experts and EE experts alone. Examples include software that is “close to metal” (such as real-time operating systems), the design of CPUs, as well as CPU-based, embedded and cyberphysical systems. Data center optimization and maintenance. Electronic design automation (including design, verification and test). Validation of large digital systems. Implementation of digital signal processing.
My qualifications: I chaired the undergraduate CE program at Michigan for several years
