Simultaneous multithreading (SMT) - Hardware organization (2)
Second: Replicate all internal buffers of a superscalar such that each buffer is bound to a specific thread.
- The issue unit is able to issue instructions of different instruction windows simultaneously to the FUs.
- Adds more changes to superscalar processors organization
- but leads to a natural partitioning of the instruction window (similar to CMP)
- and simplifes the issue and retire stages.
