Abstract: Disclosed herein is an apparatus and method for controlling nonvolatile memory. The apparatus may include nonvolatile memory and a memory controller for issuing a serial clock (SCK) to the nonvolatile memory and transferring data corresponding to a requested command to the nonvolatile memory or receiving data corresponding to a requested command from the nonvolatile memory and outputting the data to the outside through a serial-in or a serial-out in response to a read request or a write request.

Abstract: An apparatus and method for determining a discrete cosine transform (DCT) size based on a transform depth are disclosed herein. The apparatus for determining a DCT size based on a transform depth includes a prediction mode determination unit, a transform unit (TU) generation unit, and a DCT performance unit. The prediction mode determination unit determines a prediction mode in order to determine a DCT size at the root location of a coding unit (CU) present in a coding tree unit (CTU). The transform unit (TU) generation unit partitions the CU into transform units (TUs) based on a residual quad tree (RQT). The DCT performance unit performs a DCT based on the TUs.
