Lookahead carry unit
LOGICAL UNIT IN DIGITAL CIRCUIT DESIGN USED TO DECREASE CALCULATION TIME IN ADDER UNITS
Lookahead Carry Unit; Lookahead-carry unit
A lookahead carry unit (LCU) is a logical unit in digital circuit design used to decrease calculation time in adder units and used in conjunction with carry look-ahead adders (CLAs).

A carry-lookahead adder (CLA) or fast adder is a type of electronics adder used in digital logic. A carry-lookahead adder improves speed by reducing the amount of time required to determine carry bits.
LALR parser generator
PROGRAM THAT GENERATES LALR PARSERS OR COMPILERS FROM SOURCE FILES
A lookahead LR parser (LALR) generator is a software tool that reads a BNF grammar and creates an LALR parser which is capable of parsing files written in the computer language defined by the BNF grammar. LALR parsers are desirable because they are very fast and small in comparison to other types of parsers.
