A lab that studies automated design techniques for embedded systems from both the hardware and software sides.
AboutAbout the lab
Designing hardware for software and software for hardware
Hara Lab studies embedded systems from both the hardware and software sides.
The lab works broadly on highly efficient, highly reliable automated design techniques for the many kinds of embedded systems found in home appliances, automobiles, mobile phones, and more.
Key terms
- Embedded system
- A dedicated computer built into a machine such as a home appliance or automobile that controls how the machine operates
- Hardware
- The physical parts that make up a computer, such as electronic circuits and components
- Software
- A collection of instructions for running a computer: programs and their data
ResearchResearch themes
*Illustrative imageProtecting circuit designs from theft
When semiconductor manufacturing is outsourced, circuit designs risk being stolen or copied. The lab designs "logic locking," which locks a circuit so that it works only with the correct key, in a form whose security can be proven.
*Illustrative imageProtecting secrets from power consumption
Secret keys can sometimes be read from tiny fluctuations in the power consumption of devices that process encryption. The lab studies ways to automatically make the cryptographic circuits of IoT devices resistant to this attack from the design stage, and the effects of how random numbers are used.
*Illustrative imageRunning AI efficiently on small devices
To make AI usable even on devices with limited power and computing capability, the lab studies hardware-software co-design of methods that split computation between a device and a server, numerical precision tuning, federated learning across devices, and mechanisms for detecting malicious communication.
