PLEX (''Programming Language for EXchanges'') is a special-purpose, pseudo-parallel and event-driven real-time programming language. Dedicated for AXE telephone exchanges, it was developed by Göran Hemdahl at Ericsson. Originally designed in the 1970s, it has been continuously evolving since then. The language has two variants: ''Plex-C'' used for the AXE Central Processor (CP) and ''Plex-M'' used for Extension Module Regional Processors (EMRP). ==Pre-compilers== Several precompilers or code generators exist, to produce source code in ''Plex-C'' from higher level languages or graphical models. These can generate ''Plex-C'' from: * Specification and Description Language graphical representation (SDL/GR) * ''Plex-SQL'', an extension of ''Plex-C'' with database facilities * ''High Level Plex'' (HLPLEX) another extension of ''Plex-C'' Source code in ''Plex-C'' is compiled into the assembly language ''ASA210C''. The binary form of ''ASA210C'' is either interpreted by a combination of hardware and microcode, or is compiled by a Just-In-Time compiler into native machine code for a high-capacity microprocessor. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PLEX (programming language)」の詳細全文を読む スポンサード リンク
