  • Publication number: 20240111827
    Abstract: The present disclosure provides a matrix device and an operation method thereof. The matrix device includes a transpose circuit and a memory. The transpose circuit is configured to receive a first element string representing a native matrix from a matrix source, wherein all elements in the native matrix are arranged in the first element string in one of a “row-major manner” and a “column-major manner”. The transpose circuit transposes the first element string into a second element string, wherein the second element string is equivalent to an element string in which all elements of the native matrix are arranged in another one of the “row-major manner” and the “column-major manner”. The memory is coupled to the transpose circuit to receive the second element string.
