  • Publication number: 20240152321
    Abstract: A floating point pre-alignment structure for computing-in-memory applications includes a time domain exponent computing block and an input mantissa pre-align block. The time domain exponent computing block is configured to compute a plurality of original input exponents and a plurality of original weight exponents to generate a plurality of flags. Each of the flags is determined by adding one of the original input exponents and one of the original weight exponents. The input mantissa pre-align block is configured to receive a plurality of original input mantissas and shift the original input mantissas according to the flags to generate a plurality of weighted input mantissas, and sparsity of the weighted input mantissas is greater than sparsity of the original input mantissas. Each of the flags has a negative correlation with a sum of the one of the original input exponents and the one of the original weight exponents.
