- Inserts instructions from each thread into the pipeline in a round-robin fashion.
- Switches to issue instructions from another thread only when the current executing thread causes a stall.
- Contains instructions of the currently executing thread only in the pipeline.
- Requires emptying the pipeline to switch between threads.

In fine grained multithreading, the threads are executed in a round-robin fashion in consecutive cycles. For example, assume a computer can issue one instruction per clock cycle. A, B, C are three threads. The first 12 cycles of those threads are as follows. The way of these threads issuing instructions according … See more
In coarse grained multithreading, a thread issues instructions until thread issuing stops. The process is also called stalling. When a stall occurs, the next thread starts issuing instructions. … See more

Multithreading (computer architecture) - Wikipedia
The simplest type of multithreading occurs when one thread runs until it is blocked by an event that normally would create a long-latency stall. Such a stall might be a cache miss that has to access off-chip memory, which might take hundreds of CPU cycles for the data to return. Instead of waiting for the stall to resolve, a threaded processor would switch execution to another thread that was ready to run. Only when the data for the previous thread had arrived, would the previo…

Mar 26, 2021 · The main difference between Fine Grained and Coarse Grained Multithreading is that, in fine grained multithreading, the threads issue instructions in round robin manner while …
Coarse-Grained Multithreading • Switches threads only on costly stalls, such as L2 cache misses • Advantages • Relieves need to have very fast thread-switching • Doesn’t slow down thread, …
Coarse-grained Multithreading: a switch only happens when the thread in execution causes a stall, thus wasting a clock cycle. At this point, a switch is made to another thread. When this …
