V článku uvedená architektúra je založená na výpočtovom modeli "data flow", v ktorom riadenie výpočtu je založené na spracovaní toku dát. Základným prvkom DF architektúry je koordinačný procesor (CP), ktorý je zodpovedný za riadenie a organizáciu vykonávania inštrukcií. Štruktúrna organizácia CP je navrhnutá ako dynamický multifunkčný systém. Pri vykonávaní operácií môže CP prechádzať rôznymi stavmi, v dôsledku čoho táto jednotka predstavuje dynamický prúdový systém. Prechod a poradie prechodu medzi jednotlivými stavmi CP je podmienený typom spracovaného operátora pri interpretovaní prúdu operandov. Z možných typov operátorov, článok uvádza mikroprogramové riadenie pre jednovstupové operátory.

Microprogram for operand matching in DF KPI architecture

The architecture described in this article is based on the data-flow computation model, in which computation is driven by processing a flow of data. The basic element of the data-flow architecture is the coordinating processor (CP), responsible for controlling and organizing the execution of instructions. As to its structure, the CP is designed as a dynamic, multi-functional system. When executing the operations, the CP may acquire various states, therefore it is a dynamic pipelining system. The transitions and the order of the states between two transitions depend on the type of the operator processed at the time of interpreting the flow of operands. This article details the microprogram control of single-input operators.
