Method For CCITT High Level Language Program Development And Operating In Exchange Switching System

摘要

Communication software development international standard language in developing a program with seven CHILL program signal reception capability data communication between processes within the exchange system that frequently occurs to improve the target code generation and signal reception function of the operating system of the CHILL compiler for It is to be performed as efficiently.; The invention system is received when converting received case statement used for a signal received from a source file that the compiler is the development in the process of converting the source file developed as CHILL language into an object file of machine language by a compiler into object code by declaring a signal list of the null value to the global constant variable is set to the memory area in the exchange system, and generate code that is passed the address of the signal list as a parameter of the signal received service within the operating system switching system, and the received signal list in accordance with the declaration of the branch table for the address of the point to perform an operation that requires a constant value to a global variable, characterized in that set in the memory area in the switching system.; Therefore, minimizes access memory is, once the branch instruction in through the branch table is set in the global memory area to minimize the branch instruction to perform a memory access, regardless of the number of signals and to be able to run the job, the reception of signals function is optimized, thereby improving the performance of the overall switching system.
