摘要

为研究IP核的引入对三维FPGA芯片性能的影响

提出引入IP核同质和粗粒度异质两种三维FPGA结构.首先

利用二维FPGA CAD开源软件构建基于IP核和三维开关盒的三维FPGA CAD工具.然后

利用该工具从定性和定量的角度对不同堆叠层数引入IP核的同质三维FPGA结构进行性能分析.实验发现

随着堆叠层数的增加

关键路径延迟逐渐减小; 芯片总面积逐渐增加

单层芯片面积逐渐减小.与引入IP核的同质三维FPGA结构相比

粗粒度异质三维FPGA结构的关键路径延迟更小

表明该结构在减小延时方面的有效性.

Abstract

In order to fathom the effect on three-dimensional FPGA performance after IP cores are integrated

two FPGA structures are introduced in this paper: homogeneous 3D FPGAs with IP cores and coarse-grained heterogeneous ones.In the first place

we developed a new FPGA CAD tool

which is an upgrade version of a 2D FPGA CAD tool

to support FPGAs based on IP cores and 3D switch boxes

then use it to analyze the homogeneous 3D FPGA performance in different layers in terms of quality and quantity. Experiments reveal the fact that with the number of chip layer increases

total chip area will rise

in the other hand

critical path delay and chip area per layer fall accordingly. Compared to the homogeneous 3D structured FPGAs (with IP cores)

coarse-grained heterogeneous ones have better critical path delay

which proves such structure has the effectiveness on reducing critical path delay.
