A high-performance bitmap-index-based query processor on 65-nm SOTB CMOS process

This paper presents the efficient architecture of a bitmap-index-based query processor for fast data analytics on 65-nm SOTB CMOS process. The post-simulation with a supply voltage of 0.55 V indicates that the processor could operate at 125 MHz and process up to 232 million records/second in case 32 keys and queries are utilized. Furthermore, by applying the reverse body bias voltage of -2 V, the leakage current reduces up to 73 times as compared to that in normal body bias.
