Dynamically variable line-size cache exploiting high on-chip memory bandwidth of merged DRAM/logic LSIs
Koji Inoue, K. Kai, Kazuaki J. Murakami · 1999
This paper proposes a novel cache architecture suitable for merged DRAM/logic LSIs, which is called "dynamically variable line-size cache (D-VLS cache)". The D-VLS cache can optimize its line-size according to the characteristic of programs, and attempts to improve the performance by exploiting the high on-chip memory bandwidth. In our evaluation, it is observed that the performance improvement achieved by a direct-mapped D-VLS cache is about 27%, compared to a conventional direct-mapped cache with fixed 32-byte lines.
