Abstract :
This paper describes the outcomes of the NSF Grant CNS-0615085: CSR-EHS: enhancing the effectiveness of utilizing an instruction register file. We improved promoting instructions to reside in the IRF and adapted compiler optimizations to better utilize an IRF. We show that an IRF can decrease the execution time penalty of using an LO/filter cache while further reducing energy consumption. Finally, we introduce a tagless hit instruction cache that significantly reduces energy consumption without increasing execution time.
