Implicitly Multithreaded Processor (IMT)
Speculative SMT operation
How to buffer speculative data?
IMT: Most significant improvements
What does Compiler do?
Multiplexing threads on a single hardware context
Hence frequent switching, less overlap
Multiplexing: Required Hardware
Multiplexing: Implementation Issues
Register renaming: Flow
Hiding thread startup delay
LSQ Limitations: Alternative
Register file size
Searching LSQ (contd.)
So how is performance still high?
