Abstract
A matrix calculation device including a storing unit, a multiply accumulate (MAC) circuit, a pre-fetch circuit, and a control circuit, and an operation method thereof are provided. The storing unit stores a first and second matrixes. The MAC circuit is configured to execute MAC calculation. The pre-fetch circuit pre-fetches at least one column of the first matrix from the storing unit to act as pre-fetch data, pre-fetches at least one row of the second matrix from the storing unit to act as the pre-fetch data, or pre-fetches at least one column of the first matrix and at least one row of the second matrix from the storing unit to act as the pre-fetch data. The control circuit decides whether to perform the MAC calculation on a current column of the first matrix and a current row of the second matrix through the MAC circuit according to the pre-fetch data.
