单片机编程 Replacement of NXP PCA9518 wit
The outputs of the PCA9518 are immediately available as soon as there is a voltage present on thesupply >~1V and behave as described above. The power-on reset of the PCA9518A keeps the outputsturned off during power-up and maintains the high impedance of the outputs throughout the power-upcycle. The ...
单片机编程 一种8位单片机中ALU的改进设计
文章提出了一种精简指令集8 位单片机中, 算术逻辑单元的工作原理。在此基础上, 对比传统PIC 方案、以及在ALU 内部再次采用流水线作业的332 方案、44 方案, 并用Synopsys 综合工具实现了它们。综合及仿真结果表明, 根据该单片机系统要求, 44 方案速度最高, 比332 方案可提高43.9%, 而面积仅比最小的332 方案增加1.6%。在分析 ...
