Abstract
A data padding device includes an internal memory, a direct memory access (DMA) circuit and a data processing circuit. The DMA circuit performs, according to a first padding control signal, data padding in a first direction on raw data during a process of reading the raw data from an external memory to generate first-direction padding data, and stores the first-direction padding data to the internal memory, wherein the first-direction padding data includes the raw data and first padding data originated from the raw data. The data processing circuit performs, according to a second padding control signal, data padding in a second direction on the first-direction padding data during a process of reading the first-direction padding data from the internal memory to generate second-direction padding data, wherein the second-direction padding data includes the first-direction padding data and second padding data originated from the first-direction padding data.
