Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Energy efficiency is a first-order design goal for nearly all classes of processors, but it is particularly important in mobile and embedded systems. Data caches in such systems account for a large portion of the processor's energy usage, and thus techniques to improve the energy efficiency of the cache hierarchy are likely to have high impact. Our prior work reduced data cache energy via a tagless access buffer (TAB) that sits at the top of the cache hierarchy. Strided memory references are redirected from the level-one data cache (L1D) to the smaller, more energy-efficient TAB. These references need not access the data translation lookaside buffer (DTLB), and they can avoid unnecessary transfers from lor levels of the memory hierarchy. The original TAB implementation requires changing the immediate field of load and store instructions, necessitating substantial ISA modifications. Here  present a new TAB design that requires minimal instruction set changes, gives software more explicit control over TAB resource management, and remains compatible with legacy (non-TAB) code. With a line size of 32 bytes, a four-line TAB can eliminate 31% of L1D accesses, on average. Together, the new TAB, L1D, and DTLB use 22% less energy than a TAB-less hierarchy, and the TAB system decreases execution time by 1.7%.
