The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The proposed time-domain near-memory computing architecture for low-precision MAC operations achieves 7.62 TOPS/W energy efficiency in a 4x4 prototype at 1 V supply and 40 MHz operating frequency.

C2weakest assumption

That the N-pulse generator and counter-based accumulation maintain sufficient linearity and scalability when extended beyond the 4x4 prototype without significant power or area penalties.

C3one line summary

A hybrid time-domain near-memory MAC prototype using pulse-encoded inputs and current-steering DAC weights achieves 7.62 TOPS/W energy efficiency with RTL-synthesized digital blocks for portability.
