Abstract

An increase in computer throughput can be achieved by selecting certain normally programmed operations for execution by microprogramming. In a microprogramming mode of operation, the system is always executing instructions as opposed to standard programmed mode of operation which includes both the reading out of instructions and the execution of those instructions.

An increase in computer throughput can be achieved by selecting certain normally programmed operations for execution by microprogramming. In a microprogramming mode of operation, the system is always executing instructions as opposed to standard programmed mode of operation which includes both the reading out of instructions and the execution of those instructions.

This technique is expandable to computer systems operating in response to an operating system type of programming. High usage portions of the operating system's program can be implemented in microcoding. Representative portions might include l/O requests for CPU time, interrupt handling, or macro-instructions such as wait and fetch. In multiprogramming as well as multiprocessing systems, the selective implementation of portions of an operating systems type of program in microcoding reduces the amount of core storage required. This is because many users or different programs would use identical portions of an operating systems Program. Each user or each program can address the desired microcoding without the need of moving programs from bulk storage to active storage.
