432-Core Chiplet-Based RISC-V Chip Nearly Ready to Blast Into Space

The Occamy processor, which uses a chiplet architecture, has 432 RISC-V and AI accelerators, 32 GB of HBM2E memory, and is taped out. The chip is backed by the European Space Agency and is reportedly developed by engineers from the ETH Zurich and the University of Bologna. HPC wire.

The ESA-backed Occamy processor uses 216 32-bit RISC-V cores, two chiplets with an unknown number of 64-bit FPUs for matrix computation, and is powered by two 16GB HBM2E memory packages from Micron. I’m here. The cores are interconnected using a silicon interposer, allowing the dual-tile CPU to deliver 0.75 FP64 TFLOPS of performance and 6 FP8 TFLOPS of compute power.

Neither ESA nor its development partners have revealed the power consumption of the Occamy CPU, but the chip is said to be passively cooled. So it may be a low power processor.

Each Occamy chiplet has 216 RISC-V cores and matrix FPUs, with a total of about 1 billion transistors on 73mm^2 of silicon. The tiles are manufactured by GlobalFoundries using the 14LPP manufacturing process.
