Struct StdpSynapse

Source

pub struct StdpSynapse {
    pub weight: i16,
    pub trace_pre: i16,
    pub trace_post: i16,
    pub data_width: u32,
    pub fraction: u32,
}

Expand description

A synapse with STDP learning capability.

Fields§

§weight: i16

Current weight value (fixed-point).

§trace_pre: i16

Pre-synaptic trace.

§trace_post: i16

Post-synaptic trace.

§data_width: u32

Data width.

§fraction: u32

Fraction bits.

Implementations§

Source §

impl StdpSynapse

Source

pub fn new(initial_weight: i16, data_width: u32, fraction: u32) -> Self

Source

pub fn step(&mut self, pre_spike: bool, post_spike: bool, params: &StdpParams)

Update traces and weight based on pre and post spikes.

This is a simplified, hardware-friendly STDP rule:

On pre-spike: trace_pre += A_plus; weight += trace_post * rate
On post-spike: trace_post += A_minus; weight += trace_pre * rate
Traces decay over time.
