Two of the most important factors in the design of any processor
are speed and energy consumption. In this paper, we propose a new
cache architecture that results in a faster memory access and lower
energy consumption. Our proposed architecture does not require any
changes to the processor architecture, it only assume the existence of a
BTB. Using Mediabench, a benchmark used for embedded applications,
Simplescalar simulator, and CACTI power simulator,we show that our
proposed architecture consumes less energy, and have better memory
access time, than many existing cache architectures.
1 Introduction
The processor speed is advancing at a much higher rate than the memory
access speed. The cache memory is generally considered to be the only
solution to bridge the gap between the processor speed and the memory
