The lab explores highly efficient computing using reconfigurable devices.
AboutAbout the lab
Highly efficient computing with reconfigurable circuits.
The High-Efficiency Custom Circuit Design Engineering Lab studies new computing architectures that use reconfigurable integrated circuits (FPGAs).
By explicitly building reconfigurability into systems and applications, the lab aims to improve reliability and to optimize power consumption relative to computational performance.
Research themes include autonomous flight of micro drones and immersive displays with eye tracking.
In April 2026, the lab started as an independent lab, spun out from the FPGA team of the HPCS Lab.
Key terms
- FPGA
- An integrated circuit that can be freely reconfigured. It is used to build dedicated hardware specialized for a particular process
- Micro drone
- A drone weighing less than 30 g. Its battery is small, so the power available for computation is limited
- Immersive display
- A display that projects images onto a spherical screen, giving the feeling of being inside the images

ResearchResearch themes
The lab studies new computing architectures in which reconfigurability is explicitly built into systems and applications. Rather than using reconfigurable devices as a substitute for prototype chips, it aims to improve system reliability and to optimize power consumption relative to computational performance through computing methods that take advantage of being reconfigurable.
*Illustrative imageComputing Architectures That Exploit Reconfigurability
The lab studies computing methods that make use of reconfigurability, as well as highly efficient computing methods that improve system reliability and optimize power consumption relative to computational performance. It has developed a research platform called "Trefoil."
*Illustrative imageSystems That Run on Little Power
Reconfigurable devices are expected to be effective when sensor data must be processed in a short time and results returned immediately, and in systems where power is extremely limited. The lab aims to go beyond performance limits by using FPGAs to efficiently compute the elements required for autonomous flight of micro drones weighing less than 30 g.
*Illustrative imageApplications of the Systems Developed in the Lab
Applications built on the systems developed in the lab can also become research themes. Examples include an immersive display with eye tracking, a 200 Gb-class video transmission system with sub-millisecond latency, highly reliable wireless communication for mobile platforms, and petabyte-scale massively parallel storage.
