技術說明

【中文】一種矩陣乘法裝置及其操作方法。矩陣乘法裝置包括計算電路、控制電路、乘法電路以及路由電路。計算電路產生乘積累加值。控制電路接收第一矩陣的多個第一元素值。控制電路依照數值種類將這些第一元素值歸納為至少一個歸納數值。乘法電路在低功率模式中將所述歸納數值各自乘以第二矩陣的第二元素值，以獲得至少一個乘積值。路由電路在低功率模式中將所述乘積值的每一個傳輸給計算電路中的至少一個對應計算電路。 【英文】A matrix multiplication device and an operation method thereof are provided. The matrix multiplication device includes calculation circuits, a control circuit, a multiplication circuit, and a routing circuit. The calculation circuits produce multiply accumulate values. The control circuit receives a plurality of first element values of a first matrix. The control circuit classifies the first element values into at least one classification value according to the number of value. The multiplication circuit multiplies the classification values by the second element value of a second matrix in a low power mode to obtain at least one product value. The routing circuit transmits each of the product values to at least one corresponding calculation circuit in the calculation circuits in the low power mode.
