Design and management of 3D-stacked NUCA cache for chip multiprocessors
Jongpil Jung, Kyungsu Kang, Chong-Min Kyung · 2011
Power and delay induced from long on-chip interconnections are becoming major issues of chip multiprocessor design. Both network-on-chip (NoC) and three-dimensional integration are promising ways to mitigate the interconnection problem. In this paper, we explore the design of 3Dstacked non-uniform cache architecture (NUCA) with onchip network. In addition, this paper investigates the problem of partitioning shared L2 cache for concurrently executing multiple applications in order to improve the system performance in terms of instructions per cycle. The proposed design is evaluated in an integrated power, performance, and temperature simulator. Experimental results show that the proposed method enhances system performance by 23.3% and reduces energy consumption by 17.9% for 16-core processor system compared to conventional design.
