Abstract: An apparatus and method for skipping fractional motion estimation (FME) in high efficiency video coding (HEVC) are disclosed. The apparatus includes a current sum of absolute differences (SAD) acquisition unit, a redundancy determination unit, and a motion estimation skip unit. The SAD acquisition unit acquires the SAD from an integer motion estimation (IME) unit when the IME unit performs IME on a coding tree block (CTB). The redundancy determination unit determines whether or not the CTB is an estimated redundant block using the current SAD. The motion estimation skip unit provides an FME unit with an FME skip signal of the CTB depending on whether or the CTB is an estimated redundant block.

Abstract: Disclosed herein are an apparatus and method for managing cache memory. The apparatus includes one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program reads an s1-tag and an s2-tag of cache memory upon receiving an access request address for reading data in response to a request to access the cache memory, checks whether the access request address matches the value of the s1-tag and the value of the s2-tag, and reads the data from data memory when the access request address matches all of the value of the s1-tag and the value of the s2-tag.
