Fig. 5: Benchmarking of AMC against digital processors.
From: Precise and scalable analogue matrix equation solving using resistive random-access memory chips
a, Transient curves of the LP-INV circuit. The matrix in the experiment is Re(A) in Fig. 4. Five individual input vectors were tested, resulting in 20 output curves. The average response time is about 120 ns. b, Transient curves of the MVM circuit. Again, 20 output curves were collected, and the average response time is about 60 ns. Red, INV output 1; blue, INV output 2; orange, INV output 3; yellow, INV output 4. c,d, Benchmarking of computing throughput (c) and energy efficiency (d) of AMC and state-of-the-art digital processors, namely two GPUs and one ASIC. The same computing precision (FP32) was maintained for all candidates.
