The Occamy processor, which uses a chiplet architecture, packs 432 RISC-V and AI accelerators and comes with 32GB of HBM2E memory, has taped out. The chip is backed by the European Space Agency and developed by engineers from ETH Zürich and the University of Bologna, reports HPC Wire.
The ESA-backed Occamy processor uses two chiplets with 216 32-bit RISC-V cores, an unknown number of 64-bit FPUs for matrix calculations, and carries two 16GB HBM2E memory packages from Micron. The cores are interconnected using a silicon interposer, and the dual-tile CPU can deliver 0.75 FP64 TFLOPS of performance and 6 FP8 TFLOPS of compute capability.
Neither ESA nor its development partners have disclosed the Occamy CPUs' power consumption, but it is said that the chip can be passively cooled, meaning it might be a low-power processor.
