MULTIPLY-ACCUMULATE OPERATION METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18522797 titled 'MULTIPLY-ACCUMULATE OPERATION METHOD AND APPARATUS
Simplified Explanation
The present disclosure describes a method for performing a multiply-accumulate operation using an accumulation register, overflow counter, and exponent updater to handle overflow values and perform normalization and rounding.
- The method involves accumulating a value within a preset bit value of a mantissa bitwidth in a result of an addition operation of shifted first and second mantissa values.
- An overflow counter determines an overflow count based on the overflow value, which indicates when the result of the addition operation exceeds the preset bit value of the mantissa bitwidth.
- Normalization and rounding are performed based on the accumulated value in the accumulation register and the overflow count.
- The exponent updater updates the exponent using the normalized and rounded value.
