MICROCOMPUTER WITH HIGH SPEED ACCESS MEMORY AND LANGUAGE PROCESSING PROGRAM EXECUTION SYSTEM

A microcomputer having a high speed access memory and a language processing program execution system capable of producing a compact object including a high speed variable operation is disclosed. As to an input source program, variable areas used by subroutines are calculated by a variable area analyzing part, and a flow graph of an interrelation of callings of the subroutines is produced by a flow graph producing part. Then, the maximum variable area used by a whole program is calculated from the sizes of the variable areas and the flow graph by a maximum variable area detecting part. When the calculated maximum variable area size of the whole program is smaller than the memory size of the high speed access memory, an output part outputs the object information with variables allocated in the high speed access memory.
