面向AIC结构的FPGA映射工具

Mapper for AIC-based FPGAs

探索新的现场可编程门阵列（FPGA）逻辑单元结构一直是FPGA结构研究的重点方向,与非逻辑锥（AIC）作为一种新的逻辑结构成为FPGA新结构的希望。然而实现高效且灵活的映射工具同样是研究FPGA新结构中的重点环节。该文实现了一个面向AIC结构的FPGA映射工具,与当前映射工具相比,具有更高的灵活性,能够支持AIC结构参数的调节,辅助支持进行AIC单元结构的探索改进。同时,该文提出的AIC映射工具与原工具相比,面积指标提高了33%~36%。

Exploring a new logic element of Field Programmable Gate Array （FPGA） is always a key field in FPGAs＇ research, while And-Inverter Cones （AIC） is the most promising one. Implementing a highly-efficient and highly-flexible mapping tool is also an important part of exploring new FPGA architecture. In this paper, a new mapper for AIC-based FPGA is implemented. Compared with an existing mapper, the new mapper has much higher flexibility, and supports adjustments of AICs＇ architectural parameters to assit the design space exploration of AIC. Meanwhile, the new mapper provides area results 33%～36% better than the original mapper.
