LLgen, an extended LL(1) parser generator
LLgen provides a tool for generating an efficient recursive descent parser with no backtrack from an Extended Context Free syntax. The LLgen user specifies the syntax, together with code describing actions associated with the parsing process. LLgen turns this specification into a number of subroutines that handle the parsing process. The grammar may be ambiguous. LLgen contains both static and ...
متن کاملANTLR: A Predicated- LL(k) Parser Generator
Despite the parsing power of LR=LALR algorithms, e.g. YACC 1, programmers often choose to write recursive-descent parsers by hand to obtain increased flexibility, better error handling, and ease of debugging. We introduce ANTLR, a public-domain parser generator that combines the flexibility of hand-coded parsing with the convenience of a parser generator, which is a component of PCCTS 2. ANTLR ...
متن کاملAn Implementation of a Fast Threaded Nondeterministic LL(*) Parser Generator
This paper proposes separating the semantic actions’ execution from the parsing phase. The parser generates a queue of semantic actions attached with grammar rules to be visited in case of successful parsing. By this separation, the execution time of the parsing phase can be enhanced. More importantly, this will avoid the incorrect execution of semantic actions when dealing with non-determinist...
متن کاملAn Arabic Slot Grammar Parser
We describe a Slot Grammar (SG) parser for Arabic, ASG, and new features of SG designed to accommodate Arabic as well as the European languages for which SGs have been built. We focus on the integration of BAMA with ASG, and on a new, expressive SG grammar formalism, SGF, and illustrate how SGF is used to advantage in ASG.

An analog-to-digital converter for on-chip focal-plane image sensor applications. The analog-to-digital converter utilizes a single charge integrating amplifier in a charge balancing architecture to implement successive approximation analog-to-digital conversion. This design requires minimal chip area and has high speed and low power dissipation for operation in the 2-10 bit range. The inventio...
