Abstract
An improved distributed processing system for controlling the transfer of data between a terminal controller and a subsystem is described where the improvement insures wordstring consistency in a manner which is completely transparent to the subscriber subsystem. In particular, data is transferred, via a dual-bank, dual-port terminal memory where the bank selection is controlled such that any wordstring transfers between the terminal memory and the terminal controller are constrained to involve a different bank than transfers between the terminal memory and its associated subscriber subsystem. A wordstring log associated with control arbitration logic contains the dynamic state of the bank assignments for each wordstring. Two flag bits in the wordstring log provide information to the control/arbitration logic, allowing it to manage the bank selection of the terminal memory.
