A Novel Design of Bit-Slice Matrix Multiplier for RSFQ using Shadow Latch
In this paper, we demonstrated a high speed energy efficient approximate multiplier. We contemplate an approach
which is to round the operands to nearest exponent to two. The proposed system is applied for both unsigned and signed
multiplications. A 4-bit bit-slice matrix multiplier is exploited for 32-bit rapid multiple-flux-quantum (RMFQ) artificial
intelligence processor is proposed in this paper. The multiplier mainly includes bit-slice multipliers which is 4-bit and 4-bit
bit-slice adders. The unsigned integer matrixes multiplication is contrivance by control signals. The result shows that our
method simplifies the circuit complexity, truncates the hardware costs and allows extending the matrix multiplier to a
smaller or larger number of bits.
