Abstract : The system facility of an elementary machine of the Minsk 222 computer system is described as the functional units which carry out the commands of the system. These commands include the commands of transmission, input, set-up, and general unconditional transfers, and are associated with the shifting of information among elementary machines. This facility also handles the intermachine transfer of operating information. The facility consists of three basic units: a commutator, a set-up register, and systems operations unit. The commutator is composed of a commutation circuit handling the working channel, priority channel, and a synchronization channel, all of which are of the impulse type. The set-up register has a record for the current partition or subsystem of operation, as well as a circuit of potential cores for control. The systems operations unit contains an operations decoder, a central distributor of impulses, a link with the operating memory unit, a command address retriever, links with peripheral units and with the control console, register controls, control transfer devices, and a tape address calculator. The facility arrangements are discussed in some detail. (Author)
