from other threads, there is less chance of one instruction in one pipelining stage needing an output from an older instruction in the pipeline. Conceptually, it is similar to preemptive multitasking used in operating systems; an analogy would be that the time slice given to each active thread is one CPU cycle.

For example:
# Cycle : an instruction from thread is issued.
# Cycle : an instruction from thread is issued.

This type of multithreading was first called barrel
