Abstract

A number of otherwise independent modular subsystems of a processor can be adapted to share a common read-only store matrix ROS, on a time division multiplex basis, as a main source of control pulses. One way of effectively accomplishing this is to provide the controlled modules with individual ROS output buffer registers ROSDR and individual logic circuit groups for determi~ng and selecting ROS addresses, Decision and Roar. In operation each controlled module is allocated a different cycle of the RCIS control system on a time division basis. The cycling frequency of ROS is adapted to accommodate the cycling requirements of all of the controlled modules.

Multiple Use of a Read Only Storage Matrix by Time Division Multiplexing Techniques

A number of otherwise independent modular subsystems of a processor can be adapted to share a common read-only store matrix ROS, on a time division multiplex basis, as a main source of control pulses. One way of effectively accomplishing this is to provide the controlled modules with individual ROS output buffer registers ROSDR and individual logic circuit groups for determi~ng and selecting ROS addresses, Decision and Roar. In operation each controlled module is allocated a different cycle of the RCIS control system on a time division basis. The cycling frequency of ROS is adapted to accommodate the cycling requirements of all of the controlled modules. In other words, the interval defined by successive ROS cycles allocated to each controlled module must span the interval of a single cycle of operation of the respective controlled module.
