Abstract

Generation of microcode is time consuming and requires generally specific non-automated tools in order to prepare microcode modules, i.e., programmable read only memory (PROM) modules. The system described, which is used as a tool for an engineering model to be developed, can also be used to create PROM modules in case of microcode modification. The present system uses an information handling system (IHS), say, an IBM System/370, provided with a Direct Communication Feature (DCF), a Channel Addressable Control Unit (CACU) or similar unit, and a display I/O terminal for the microprogrammer, as represented in the figure. This IHS is connected to the system whose part of the microcode sections must be created or modified, say, a Line Switching System (LSS).
