mrve32-snn
SNN layer accelerator device module for the MRVE32 RISC-V emulator: a behavioural (golden) model of a memory-mapped spiking-layer accelerator, spec v0 draft.
- LIF/IF neurons,
i16saturating potentials,i8weights, reset by subtraction - one layer per START, local SRAM (spikes, weights, potentials, bias)
- analytical cycle model, completion interrupt (MEIP)
- the computation sits behind a swappable
SnnBackend(default:ReferenceLif)
It plugs into the emulator through the public device interfaces only
(BusDevice in Rust, the device C ABI in Python), like any third-party device;
see docs/devices.md.
Rust
use mrve32::Bus;
use mrve32_snn::{SNN_WINDOW_SIZE, SnnAccelerator, SnnConfig};
let mut bus = Bus::new();
bus.map_device(0x1000_0000, SNN_WINDOW_SIZE, Box::new(SnnAccelerator::new(SnnConfig::default())))
.unwrap();
Python
pip install ../.. # mrve32 core first (not on PyPI yet)
pip install .
from mrve32 import Emulator
from mrve32_snn import SnnAccelerator, SnnDriver, reference_step, pack_spikes
emu = Emulator()
emu.map_device(0x1000_0000, SnnAccelerator(max_inputs=1024, max_outputs=512))
dev = SnnDriver(emu, 0x1000_0000) # host-side driver over the emulated bus
reference_step is the NumPy golden model of one timestep; the tests check
the Rust model against it bit-exactly.
