应用背景Abstract—Leros is a tiny microcontroller that is optimized for current low-cost FPGAs. Leros is designed with a balanced logic to on-chip memory relation. The design goal is a microcontroller that can be clocked in about half of the speed a pipelined on-chip memory and consuming less than 300 logic cells. The architecture, which follows from the design goals, is a pipelined 16-bit accumulator processor. An implementation of Leros needs at least one on-chip memory block and a few hundred logic cells. The application areas of Leros are twofold: First, it can be used as an intelligent peripheral device for auxiliary functions in an FPGA based system-on-chip design. Second, the very small size of Leros makes it an attractive softcore for many-core research with low-cost FPGAs.关键技术The smallest core is comparable to Leros and can be implemented

嵌入式设备使用的FFT算法。基于2基的库里-图基础。 以数据类型，以s32替换float。 误差可控。有误差范围的宏定义决定。 在STM32F103系列CPU上，以72MHz运行，256点，需要不足5ms时间。 算法在数据转移方面还有进一步的优化空间。若使用大型的固定值的查找表，大概还能节省1ms左右。
