Area consumption (cell area plus wiring) of one neuro-synaptic core and its components in the GF-22 nm technology node, using Cadence Genus tool.
| Module | Cell count (k) | Area(kμm2) | Area (%) |
|---|---|---|---|
| RISC-V | 11 | 10.9 | 2.3 |
| SMPU | 1.7 | 2.1 | 0.4 |
| NoC | 9.8 | 12.1 | 2.6 |
| RV peripherals | 2.9 | 2.4 | 0.5 |
| NPE | 5.6 | 6.3 | 1.3 |
| Event generator | 7.3 | 9.7 | 2.1 |
| Loop buffer | 8.9 | 10.5 | 2.2 |
| Inst Mem | 1 × 256 kb | 41.2 | 8.7 |
| Data Mem | 8 × 256 kb | 330.7 | 70 |
| Total core | 92.6 | 472.4 | 100 |
We configured this neuro-synaptic core to have 8 NPEs, 22 kb of register-based memory, 2 Mb of Data Memory, and 128 kb of instruction memory with 500 MHz clock frequency.
