A pipeline architecture oriented towards efficient multitasking

Consider a pipeline system, operating in a multitasking environment, with the following property: during the execution only one instruction of each program in the ready status is present in the pipeline stream. In this way we obtain the logical independence between the instructions being executed in the pipeline. A simplified schema of an architecture based on the above idea is presented here. The system has an high degree of modularity and is particularly suited for multitasking applications.
