When math meets hardware: Optimizing real-time 3D sonar on minimal FPGA resources

Water Linked develops compact, yet high-performance underwater navigation systems. At the core of our technology lies a strong synergy between advanced mathematical modeling, signal processing and deep FPGA expertise.

In this talk, we share insights from developing the Sonar 3D-15 — a real-time 3D imaging sonar built on a surprisingly small Altera FPGA. Achieving real-time 3D point clouds on limited hardware required extreme optimization, creative use of FPGA architecture, and smart algorithmic design.We will also show how modern verification tools like cocotb support efficient testing and optimization.

The result: a high-performance sonar that demonstrates how mathematical insight and hardware design can combine to achieve what many would consider impossible.

‘No CPU, No Compromise: Building Reliable FPGA Crypto for Space‘

EIDEL is a Norwegian leading designer and supplier of electronics for the defence and aerospace markets. The flexibility and versatility of FPGAs is a major advantage for demanding and low volume products that we deliver. While the current trend on FPGA development is to tightly integrate hardware and embedded software, we have decided for our Nanosatellite Crypto Unit not to use any CPU. This offers advantages when high reliability is required, and modern methodologies for design and especially testing makes the process easier than ever. By focusing on modularity and reuse of functional blocks, we have developed a highly capable and robust system, fully exploiting the parallelism and flexibility inherent to FPGAs.
