          HI-TECH C compiler for PIC18 MCUs implements the optimizations of Omniscient Code Generation? (OCG) - a whole-program compilation technology - to provide denser code and better performance for development on PIC18 MCUs.

          This ANSI C Compiler available in three operating levels. To compare the optimizations and features of each, please see the table below.
