Abstract(in English) | The three-dimensional (3D) integrated circuit technology is expected to continually improve the LSI (Large Scale Integration) performance when the process miniaturization closing to the physical limitation. However, because the TSV (Through Silicon Via) that used to make the inter-layer vertical connection has much larger area than the transistor, there is a tradeoff between the connectivity and the area overhead. Especially the FPGA (Field Programmable Gate Array) requires large amount of routing resources, it is unrealistic to make the same number of connections vertically as horizontal connections. We have proposed a two-layer compact 3D FPGA with the face-down integration (the base FPGA) method in a previous research. In this paper, we stack multiple base FPGAs with the face-up method, and propose inter-layer high-speed communications with TSV serial connections. The proposed architecture improves FPGA performance by using only few TSVs. The evaluation results show that the proposed 3D FPGA reduces 60% area at the maximum when compared with a 2D FPGA. |
