Latest Patents

Lance H Johnson holds a patent for a "Microinstruction substitution mechanism in a control store." This invention involves a microinstruction control storage mechanism that includes a read-only store (ROS), a writable control store (WCS), a first cycle control store, and a reserved portion of main storage. The ROS is designed to store frequently used sequences of microinstructions, which remain unaltered during operation. Less frequently used sequences are stored in the reserved portion of main storage. The invention allows for efficient paging of microinstructions into the WCS, saving one cycle of execution for each machine instruction by directly accessing microinstructions from the first cycle control store.
