Definitions

  • a typical computer system consists of a number of modules or components.
  • Computer systems typically include a central processing unit (CPU) such as a microprocessor.
  • the microprocessor is a program-controlled device that obtains, decodes and executes instructions.
  • a computer system also includes storage components for storing system operating software, application program instructions and data. These storage components may be read only memory (ROM), random access memory (RAM), or mass storage such as disk or tape storage, or any other suitable storage means.
  • main memory The memory component known as main memory is a scarce resource that is dynamically allocated to users, data, programs or processes.
  • Memory users competing for this scarce resource include application programs, TSR's ("terminate and stay resident" programs) and other processes.
  • application programs include word processors, spreadsheets, drawing programs, databases, etc.
  • Certain application programs may be stored in ROM. Generally, however, application programs are stored on a mass storage device, such as a disk drive. Upon initialization, application programs that are to be executed by the CPU are transferred from mass storage to RAM.
  • Figure 7 is a flow diagram illustrating the calling of a module in the invention.
  • the present invention reduces conventional memory requirements by providing a method and apparatus for TSR's and other programs to share space in conventional memory.
  • the TSR's and programs are configured as "modules" and a module manager controls the swapping of modules into and out of conventional memory.
  • a module manager controls the swapping of modules into and out of conventional memory.
  • only one module is resident in conventional memory at any one time.
  • the other modules are stored in extended memory or expanded memory. This avoids time consuming and performance reducing disk swaps.
