ARM Architecture Reference Manual The purpose of this manual is to describe the ARM instruction set architecture, including its high code density Thumb® subset, and three of its standard coprocessor extensions: • The standard System Control coprocessor (coprocessor 15), which is used to control memory system components such as caches, write buffers, Memory Management Units, and Protection Units. • The Vector Floating-point (VFP) architecture, which uses coprocessors 10 and 11 to supply a high-performance floating-point instruction set. • The debug architecture interface (coprocessor 14), formally added to the architecture in ARM v6 to provide software access to debug features in ARM cores, (for example, breakpoint and watchpoint control).-ARM Architecture Reference Manual The purpose of this manual is to describe the ARM instruction set architecture, including its high code density Thumb® subset, and three of its standard coprocessor

在S3C2410上通过对红外多功能口进行配置实现红外收发功能-S3C2410 adopted in the infrared multi-function I realize infrared transceiver configuration function

本示例描述如何使用 ADC3 和 DMA 传输不断 转换后的数据从 ADC3 到内存。 ADC3 配置为连续转换 channel7。 每次转换结束时的 DMA 传输，在循环模式中， 转换后的数据，ADC3 博士从注册到 ADC3ConvertedValue 变量。 在此示例中，系统时钟是 144 兆赫，APB2 = 72 兆赫和 ADC 时钟 = APB2/2。 由于 ADC3 时钟是 36 兆赫和采样时间设置为 3 个周期，转换 12 位数据的时间是 12 个周期，所以总转换时间是 (12 + 3） / 36 = 0.41us(2.4Msps)。
