Joint Multiplier–Adder Approximation with Flag-Based Error Recovery for BF16 Digital Compute-in-Memory
Digital computing-in-memory (DCIM) provides deterministic floating-point computation but incurs substantial area and power overhead from replicated mantissa multipliers and adder trees. This work proposes an error-recoverable BF16 DCIM arithmetic unit that jointly approximates a 2-bit multiplier and the first adder sta...
