DATA TEMPORARY STORAGE APPARATUS, DATA TEMPORARY STORAGE METHOD AND OPERATION METHOD

摘要

A data temporary storage apparatus includes a moving unit coupled to a first storage unit and multiple second storage units. The moving unit receives a moving instruction having contents including a read address, a destination address and a predetermined moving rule. The moving unit further executes the moving instruction to fetch input data by row from the first storage unit according to the read address, and to temporarily stores one after another in an alternate and sequential manner the data in each row to each of the second storage units indicated by the destination address. The data moving, data reading and convolution approaches of the present invention implement in parallel data moving and a convolution operation, achieving a ping-pong operation of convolution units and enhancing convolution efficiency, while reducing memory costs since configuring two data storage spaces in a memory is not necessary.
