processor with its instruction memory, data memory, clustered register file,
and different issue slots. The following subsections show some of the techniques
to reduce the energy in such a platform within one core.
8.4.1 Register file
In processors, mostly the register files are clustered or centralized or
banked [23]. This is one of the most efficient ways to reduce power consump-
tion in the register file. Such a ...
