Competitive landscape

Digital ASIC accelerators (Tenstorrent, Groq, Cerebras) dominate on programmability and precision; neuromorphic (Intel Loihi, IBM NorthPole) overlaps on event-driven, low-power inference. Photonic digital interconnect is adjacent but distinct. In-memory computing (SRAM/DRAM analog) competes at the edge.

Analog / In-Memory Computing

Performing the multiply-accumulate of neural inference inside the memory array (memristor, SRAM, capacitor or flash crossbars) rather than shuttling data to a digital ALU, trading numerical precision for a large energy-per-MAC win. The architectural answer to the memory-bound-AI problem that Memcapacitor Compute Memory Bound Ai and Hbm Free Inference Architectures bet on; adjacent to but distinct from digital Processing-in-Memory (PIM).
