LCU may refer to: A US Navy hull classification symbol: Landing craft utility (LCU) Largest coding unit, the basic processing unit of the High Efficiency Video Coding (HEVC) video standard; Last Chance U, a documentary series; Lego City Undercover, a video game
The first computer to have multiple parallel discrete single-bit ALU circuits was the 1951 Whirlwind I, which employed sixteen such "math units" to enable it to operate on 16-bit words. In 1967, Fairchild introduced the first ALU-like device implemented as an integrated circuit, the Fairchild 3800, consisting of an eight-bit arithmetic unit ...
[1] [2] CTU is also referred to as largest coding unit (LCU). [ 3 ] A CTU can be between 16×16 pixels and 64×64 pixels in size with a larger size usually increasing coding efficiency.
In the following table, for each country/territory, WB figures shows revenue, grants, and expense, expressed in current LCU (Local Curency Units) and as percentage of GDP. Sorting is alphabetical by country code, according to ISO 3166-1 alpha-3.
The United States Navy built the LCU 1466, 1610 and 1627 classes after World War II. [44] Seventy old LCUs (likely ex-LCTs) were retired from amphibious duties and reclassified as Harbor utility craft (YFU) .
The contract announcement noted that the LCU 1700s will recapitalize the LCU fleet as a similarly rugged steel craft (to the LCU 1610) with a design life of 30 years. [25] The similarities of these two classes of ships will help the U.S. Navy to improve efficiency and reduce cost of the training programs, operations and overall ownership cost.

By combining 4 CLAs and an LCU together creates a 16-bit adder. Four of these units can be combined to form a 64-bit adder. An additional (second-level) LCU is needed that accepts the propagate and generate from each LCU and the four carry outputs generated by the second-level LCU are fed into the first-level LCUs.
