Operating system for management of memory files - has sequencing unit, which generates command signals from request signals, with three identification and one address memory

摘要

The system is used in data transmission where data are transmitted by packet switching. The system has its own time base and has a rapid cycle time for its operations. The system utilises a sequencing unit to deliver control signals to the functional units. The sequencing unit comprises a sync. register which operates when various demand and initialisation signals are present. A memory receives signals from the register to decode the commands and to control an address register. The address register controls a memory for microprogrammes comprising micro instructions which are addressed by the functional storage unit. The number of lines for memory management may be varied between 0 and 256 by one single operator.
