  • Patent number: 4025904
    Abstract: The invention relates to context switching wherein the memory address of the workspace of a problem program is stored in the memory workspace of an interrupt program. In a more specific aspect, workspace in memory stores a problem program workspace pointer, program counter contents and contents of a status register upon occurrence of an interrupt. The location of a workspace in main computer memory is referenced by the contents of a workspace pointer register. Upon occurrence of an interrupt, the contents of the register are stored in one element of a new workspace in main memory while referencing the new workspace by loading new contents into the workspace pointer register.
