A microprogrammed data communications procedure controller

摘要

This paper describes a microprogrmmaed data communications management. It is divided into three sections.1) presentation of the information structure and how current procedures work in data communications. 2) design and architecture of a microprogrammed controller executing the previous functions, avoiding most of software interventions during a transmission. 3) description of the interface between the software communications and the controller on the one hand and the relations between the different parts of that controller on the other hand. This architecture permits the use of low cost microprocessor and hardware and can use a standard channel for data communications.
