MECA-CiM: A Shared-MicroExponent-aware Configurable Analog Compute-in-Memory Macro for Efficient Inference
An analog CiM accelerator based on the SMX6 format, which extends the block floating-point representation with a lightweight microexponent shared by pairs of values is presented, demonstrating that micro-exponent-aware analog CiM with configurable granularity is an effective and practical design point for energy-effici...
