Extended Data Fig. 10: System performance estimation.
From: An analog-AI chip for energy-efficient speech recognition and transcription
To calculate processing time for RNNT on an integrated system as described in Fig. 6, (a) a simulator based on the MAC runtime on the actual chip and plausible digital processing is considered based on (b) specific timing assumptions stemming from our experiment and prior architectural work20. (c) Detailed breakdown of operations and energy across the 5 chips, including additional digital operations required to process activations from chips. (d) Total on-chip and off-chip number of operations and energy, including measured analog operations (this paper) or estimates for digital ops20. (e) Comparison with MLPerf submissions on RNNT shows a 14 × advantage in energy-efficiency.
