Sampled storage

Reads a snapshot at each sample, then commits the enabled write for the next sample. Each block instance owns independent typed storage.

Behavior

y[k] = stored snapshot[k]. snapshot[k+1] = write[k] if enabled[k]; otherwise snapshot[k].

Connected concepts

Limits and interpretation

  • One writer per local storage declaration. Reads use the current snapshot; enabled writes become visible at the next sample.

Reference basis

This software operation is defined by its public contract and worked example; no external research result is claimed.
