Micro programming system

Abstract

Abstract PURPOSE: To obtain the micro programming system which can independently be controlled for the internal operation, by coverting the instruction code from external unit into the sequence address code of the memory unit with the code converter. CONSTITUTION: This program constitution is simplified that it consists of the control section, EXIT processing and its subroutine, by excluding the routines related to interruption and managing programs conventionally provided. In place of the interruption function, the code converter 11 is provided at the interface section between the micro processor and the processing unit CPU, and keyboard KB. The converter 11 assigns the address code to the instruction code from CPU and KB in the order of them and performs code conversion. Further, the head address of the input instruction is read out by locating each operation routine in separate address, to operate the internal operation through independent formation, alteration and addition.
