Operating Systems: Internals and Design Principles provides a comprehensive and unified introduction to operating systems topics. Stallings emphasizes both design issues and fundamental principles in contemporary systems and gives readers a solid understanding of the key structures and mechanisms of operating systems. He discusses design trade-offs and the practical decisions affecting design, performance and security. The book illustrates and reinforces design concepts and ties them to real-world design choices through the use of case studies in UNIX and Windows.

(2) 从陀螺仪中获取原始数据并处理; (3) 更新数据并输出。 2. 代码分析 官方的驱动主要是了 MPL软件库(Motion Processing Library),要移植该软件库我们需 要为它提供 I2C 读写接口、定时服务以及 MPU6050 的数据更新标志。若需要输出调试信 息到上位机,还需要提供串口接口。 I2C 读写接口 MPL库的内部对 I2C 读写时都使用 i2c_write 及 i2c_read 函数,在文件“inv_mpu.c” 中给出了它们的接口格式,见代码清单 43-1。 代码清单 43-9 I2C 读写接口(inv_mpu.c 文件) 1 /* The following functions must be defined for this platform: 2 * i2c_write(unsigned char slave_addr, unsigned char reg_addr, 3 * unsigned char length, unsigned char const *data) 4 * i2c_read(unsigned char slave_addr, unsigned char reg_addr, 5 * unsigned char length, unsigned char *data) 6 */ 7 8 #define i2c_write Sensors_I2C_WriteRegister 9 #define i2c_read Sensors_I2C_ReadRegister 这些接口的格式与我们上一小节写的 I2C 读写函数 Sensors_I2C_ReadRegister 及 Sensors_I2C_WriteRegister 一致,所以可直接使用宏替换。 提供定时服务 MPL软件库中使用到了延时及时间戳功能,要求需要提供 delay_ms 函数实现毫秒级延 时,提供 get_ms 获取毫秒级的时间戳,它们的接口格式也在“inv_mpu.c”文件中给出, 见代码清单 43-2。 代码清单 43-10 定时服务接口(inv_mpu.c 文件) 1 /* 2 * delay_ms(unsigned long num_ms) 3 * get_ms(unsigned long *count) 4 */ 5 6 #define delay_ms Delay_ms 7 #define get_ms get_tick_count 我们为接口提供的 Delay_ms 及 get_tick_count 函数定义在 bsp_SysTick.c 文件,我们使 用 SysTick 每毫秒产生一次中断,进行计时,见代码清单 43-11。 代码清单 43-11 使用 Systick 进行定时(bsp_SysTick.c) 1 2 static __IO u32 TimingDelay; 3 static __IO uint32_t g_ul_ms_ticks=0; 4 /** 5 * @brief us 延时程序,1ms 为一个单位 6 * @param 7 * @arg nTime: Delay_ms( 1 ) 则实现的延时为 1 ms 8 * @retval 无 9 */ 10 void Delay_ms(__IO u32 nTime)

EA电动工具 该项目是Visual Studio 2015项目,为Sparx System EA添加了一些新功能。 为了使用此项目(直到完成安装程序),您将必须添加注册表项并重新启动EA才能看到加载项。 基本上,EA Addin流程如下所示: 创建并签署程序集以实现正确的COM方法 将其放入GAC 添加一个注册表项,以便EA加载它。 利润 有两种安装方法: 从获取最新的安装程序 在VS中以管理员身份手动生成项目,然后手动添加注册表项。 如何使用它 现在,当我在攻克它时,首先需要一些主要功能。 可以导出到excel的可追溯性报告视图 通过删除空格并使用html标记格式化列表和段落的格式,可以更好地编辑文档中的粘贴内容。 启用了减价功能的注释部分,与注释列无关。 新评论类型的降价编辑器。 Markdown插件可停靠窗口,以帮助您方便地显示Markdown注释。 可追溯性报告

作者: Bottacchi, Stefano 出版年: 2009-1 页数: 854 定价: 1658.00元 ISBN: 9780470060612 内容简介 · · · · · · A comprehensive reference to noise and signal interference in optical fiber communications Noise and Signal Interference in Optical Fiber Transmission Systems is a compendium on specific topics within optical fiber transmission and the optimization process of the system design. It offers comprehensive treatment of noise and intersymbol interference (ISI) components affecting optical fiber communications systems, containing coverage on noise from the light source, the fiber and the receiver. The ISI is modeled with a statistical approach, leading to new useful computational methods. The author discusses the subject with the help of numerous applications and simulations of noise and signal interference theory. Key features: Complete all-in-one reference on the subject for engineers and designers of optical fiber transmission systems Discusses the physical principles behind several noise contributions encountered in the optical communications systems design, including contributions from the light source, the fiber and the receiver Covers the theory of the ISI for the binary signal, as well as noise statistics Discusses the theory and the mathematical models of the numerous noise components (such as optical noise, photodetection noise and reflection noise) Introduces the frequency description of the ISI and provides new calculation methods based on the characteristic functions Provides useful tools and examples for optimum design of optical fiber transmission networks and systems This book will serve as a comprehensive reference for researchers, R & D engineers, developers and designers working on optical transmission systems and optical communications. Advanced students in optical communications and related fields will also find this book useful.
