应用背景在STM32F105和STM32F107互连型系列微控制器之前，意法半导体已经推出STM32基本型系列、增强型系列、USB基本型系列、互补型系列；新系列产品沿用增强型系列的72MHz处理频率。内存包括64KB到256KB闪存和 20KB到64KB嵌入式SRAM。新系列采用LQFP64、LQFP100和LFBGA100三种封装，不同的封装保持引脚排列一致性，结合STM32平台的设计理念，开发人员通过选择产品可重新优化功能、存储器、性能和引脚数量，以最小的硬件变化来满足个性化的应用需求。关键技术本实验将实现如下功能：开机先检测字库是否存在，如果检测无问题，则对VS1053进行RAM测试和正弦测试，测试完后开始循环播放SD卡MUSIC文件夹里面的歌曲（必须在SD卡

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
