Microcomputer with high speed memory and for this purpose a compiler optimisierter

摘要

PURPOSE:To obtain a microcomputer provided with a language processing program executing system which can make high-speed variable operation and can produce a compact object. CONSTITUTION:A variable area analyzing section 107 calculates the variable area of each subroutine on an inputted source program and a flow graph preparing section 108 prepares a flow graph indicating the correlation between the call of each subroutine. Then the maximum variable area detecting section 109 calculates the maximum variable area from the size of the variable areas and flow graph. When the calculated maximum variable area is smaller than the area of a high-speed access memory 110, an output section 105 outputs object information which allocates variables to the memory 110.
