SMT features for multithread for faster switching

[flhofer]

Consider multithreading for cores, dividing maximum load through threads, but still using the advantage of the faster pipes

[flhofer]

Steps should be

• SMT for system cores (selective SMT)
• SMT for RT-cores with reduced scheduling (remember, only registers and pipes are doubled)

[flhofer]

Strategy -> Use main (first thread) for all RT threads, remaining for their siblings = should avoid priority race. To test
