List of terms.

Term	Meaning
𝐸𝑠𝑝𝑚𝑟	Energy consumed during a reading from SPM.
𝐸𝑠𝑝𝑚𝑤	Energy consumed during a writing into SPM.
𝑁𝑠𝑝𝑚𝑟	Reading access number to SPM.
𝑁𝑠𝑝𝑚𝑤	Writing access number to SPM.
𝐸𝑖𝑐𝑟	Energy consumed during a reading from instruction cache.
𝐸𝑖𝑐𝑤	Energy consumed during a writing into instruction cache.
𝑁𝑖𝑐𝑟	Reading access number to instruction cache.
𝑁𝑖𝑐𝑤	Writing access number to instruction cache.
𝐸𝑑𝑟𝑎𝑚𝑟	Energy consumed during a reading from DRAM.
𝐸𝑑𝑟𝑎𝑚𝑤	Energy consumed during a writing into DRAM.
𝑁𝑑𝑟𝑎𝑚𝑟	Reading access number to DRAM.
𝑁𝑑𝑟𝑎𝑚𝑤	Writing access number to DRAM.
𝑊𝑃𝑖	The considered cache write policy: WT or WB. In case of WT, 𝑊𝑃𝑖=1 else in case of WB then 𝑊𝑃𝑖=0.
𝐷𝐵𝑖𝑘	Dirty Bit used in case of WB to indicate during the access 𝑘 if the instruction cache line has been modified before (𝐷𝐵𝑖=1) or not (𝐷𝐵𝑖=0).
ℎ𝑖𝑘	Type of the access 𝑘 to the instruction cache. In case of cache hit, ℎ𝑖𝑘=1. In case of cache miss, ℎ𝑖𝑘=0.
