• Optimization of FPGA logic mapping to match limited available resources

Key technologies and skills:

Fast analog interfaces between digital logic and photonic circuits using amongst others, state-of-the-art RF-SOC technology of AMD. Synthesis of complex mathematical models into RTL using high-level-synthesis (HLS) techniques.

Photonics driven quantum secure encryption engine:

Optalysys (www.optalysys.com) has developed a photonic implementation of a cryptography solution using a fully homophormic encryption (FHE) method. FHE requires a massive computational power and as a result lots of energy. Where the computational effort is solved by the photonics chip, still the data needs to be exchanged with the photonics chip using electronics interfaces running at high speeds.

FHE is based on Fourier Transform (FT) and Number Theoretic Transform (NTT) functions. The Etile™ photonic chiplet is the core of the optical processing, implementing the FT/NTT. A constellation of Etile™ chiplets and FPGA-based electrical interfaces enable this encryption technology to be applied in real-world applications that were not feasible before.

TOPIC contribution and know-how:

TOPIC is responsible for the analog data interfacing between the photonic chip and the controlling FPGA, with the future goal of the electronics miniaturization of the FPGA solution into the data center infrastructure. The communication with the Optalysys FHE photon chip requires an extreme data bandwidth. Using the latest state-of-the-art AMD RFSOC technology, this connectivity is implemented.

The communication with the FHE device requires data pre- and post- processing, involving complex mathematical operations. These operations have to match the required communication data rates. With the domain know-how of homomorphic encryption of Optalysys, TOPIC implements the required mathematical operators, modelled using untimed abstract C/C++ models into logic gates using the AMD high-level synthesis technique.
